I don?t get these stereotypes

[Sandvich Harvie]

I live in a place were theses thing aren?t ?normal? so im not get a few jokes, can you tell me what they mean if you know:
- Pink shirt, popped collar
- Brown trench coat, leaning on a lap-post, flipping coin.
- (this could be the same of the forma) Brown trench coat, no pants?
- Shirt tucked in, glasses

Thanks for your help

-gay or preppy rich kid
-cool detective, I see the pop culture reference but now how this relates to an actual stereotype of someone you would see
-Either a that 70's show reference or a pedophile either way keep this guy off your block
-and finally

FYI this is a very low content thread

the third thing is the kind of person who flashes a school bus like has happened 3 times in my town.
As for the last one, sounds like me when I was in ROTC (a massive nerd). After I got out of that crappy class (which if I'm lucky will get a lot more crappy for them if I get to ride a horse in front of them at next years christmas parade *evil laughter*) I never had my shirt tucked in. It is though suppossed to be a geek/nerd which is better then the stupid, muscular jock.

umm, I don't think the last one means a Nerd really, but perhaps stereotypically it is a nerd but thinking back to the 1930's every male child would take their shirt in and some had glasses, also it could indicate in a modern society someones parents/guardians/family retain an older lifestyle.
