Most immature thing you've ever done?

[KaiRai]

bought a nerf gun.
it was on sale, instead of the usual 50 it was 20 euros (nerf abomination blaster if anybody is interested)

it is awesome, it shoots big arse rockets.

Same, my mate was back from his RAF infantryman training for the weekend and we were bored...So we went and bought 4 nerf guns, went round his, put his sofa and cofee table on opposite sides of the room and had a seige!

Played the "penis game" at church camp, where I proceeded to yell it out.

That one definitely surprised everyone in the group, since I'm normally the reserved, mature one.

Hmm that's different to the penis game me and my mate play. We eavesdrop onto passing people's conversations and replace a random word with the word "penis" and repeat the sentence back. Hopefully while the other people are still within earshot. It's surprisingly good for laughs.

The most immature thing I've ever done is either needlessly resort to "your mother" jokes when I can't think of anything to say, e.g. "No way you could do 50 push ups man!" "Oh yea! Well... neither can your mother!", or on one cold winters afternoon draw a giant cock on my pub window in the condensation for all passers by to see.

I should really grow up...

If you grow up, you're not having fun. "You're only juvenile once, but you can be delinquent forever."

I soaked my sister's pillow in cordial then froze it after she pinched my last 50 bucks from my wallet.

I should add that this happened only a few weeks ago, and at 30, I should probably be over doing revenge pranks.

Spoiler: I'm warning you.

Dude, If I ever become evil, that will SO be the way my tower looks. Intruders will laugh to death.

But, the last immature thing I did was draw a penis in the snow during our family's ski trip last year.

when my teacher said homo erectus in a lesson, me and my friends started laughing.

 

[TheRightToArmBears]

Wandering around Leeds festival with my friends, firing raw sausages across the field of tents out of a manapult.

 

[matnatz]

[Gerazzi]

when my teacher said homo erectus in a lesson, me and my friends started laughing.

I hope to god you know what it means, though.

I won a technical victory over my math teacher, yelled "TECHNICAL VICTORY!" and high-fived the nearest classmate.

If I ever don't laugh when an archaeologist or somebody says that in a perfectly serious voice I want you to kill me because I'm already dead inside.

 

[manicfoot]

Walking around a festival asking anyone I saw if they were David Bowie.

 

[Eskay]

Me & Sky14kemea giggled everytime the name "Cockfosters" was spoken on a train that terminated there during Escapism.

And, a few months ago, when it was snowing. Me and a friend built this in the middle of town.

Spoiler: I'm warning you.

I'm sorry, "Cockfosters?"

It's a stop on the London Underground...

Ah, alright.

You two must have some self-control, then. I know I'd let out a full laugh if I heard that on a train.

Its my closest tube stop, my girlfriend still laughs at it, thats after 2 years.

There's a sign near it on the M25 that points the way to town, some genius started replacing the second O with an E, the sign read Cockfesters... absolutely brilliant.

The council tried to cover it up, he changed it back and theres been an ongoing struggle about it for ages. The guy has started printing out E's in the right font to stick on, it actually looks real now.

 

[Rascarin]

I went to an arts and crafts shop and posed all those little wooden mannequin things in indecent positions.

Pure win, right there. He deserves a medal for that.

 

[JRCB]

Well, yesterday my friend put a giant box of Malbros (not sure how to spell) on her head.

Most immature thing? Probably laughing at my science teacher when she pronounced her "V"s as "W"s, and repeating it.

Not much, but I'm fairly mature.

Oh wait! We had a dinner conversation (which I started) about scented douchebags.

 

[SpikeyGirl]

I laughed at a picture in my biology book,

No not the page with penises, the one about organisms with a hole that said 'insert wood here'

Also me and my class spent a lesson rubbing out bit of words on the board to make words like 'cock'

 

[Garzo]

Shit myself then cried about it afterwards. In my defence I was only 3 months old at the time.

[LeonLethality]

with 4 other freand we walked down a walking-bridge crouched snapping our fingers from side to side like greasers =D was pretty immature dont get me started on the other things I have done, please don't

 

[Chinchama]

Taking the foam swords in a Wal-mart and then going around the store sword fighting from isle to isle.

When tired enough I turn anything into a sexual innuendo and I mean anything.

Taking what someone has just said to me, repeating it back, and then working the phrase "shut your mouth" somewhere into it.

[edit] Look at 4chan.
