"Great Scott!" (Your spoken phrases.)

[Jake0fTrades]

Son of a Montague!

Ah! Shakespeare humor!

 

[Jake0fTrades]

"You should write a book."

Often said in an incredibly dry tone to imply that what you said is in no way interesting.

 

[Vesuvius Hetlan]

"Oh my battle-fleet gothic lolita complex!" A surprisingly effective variant for "Oh my god" however "Oh my lack of god" also works pretty well.

"This is my best thought out plan yet." when preparing to enact on something particularly stupid.

"Shit fuck.", "Emperor damn it.", are pretty good cover all combi-obscenity.

"Oh bloody hell!" -- Too much British television does weird things to you...
"Fantabulous..." -- Usually said in a sarcastic manner.
"Awesomecakes!!" -- Usually NOT said in a sarcastic manner.
"Son of a breakdancing squirrel!" -- One of my strange, nonsensical euphemisms.
"Son of a Bohemian hillbilly!" -- Another of my eccentric euphemisms, although it's not used nearly as much as the breakdancing squirrel.

 

[Sir Strange Of The House Lycan]

HOLY BUGGERNUGGETS is my favourite phrase of surprise...

One I use a lot (especially if I'm in a situation where I don't want to blasphemy/swear) is: Jeannie McIntyre and her three uncles!

I don't know where or when I came up with it but it's stuck around since childhood.

 

[Ulvai]

In english - "Seriously?" picked this one from a TV Show I watched in Britain, "Leverage", and "For crying out loud!" repeating after Jack O'Neill from "Stargate: SG-1". I don't want to translate the things I'd say in my native tongues.
