I'm writing a work of fiction that takes place in the USA. I have never been to the USA, though.

While this might be considered faggotry I will still not refrain from doing it and I need your help.
There will be youth language involved and I need commonly used expletives that boys between the age of 18 - 24 or so would use when insulting each other on a friendly basis.

All I can come up with is 'Jerk'.

Thanks for your help. The attached picture is not remotely related to the inquiry.
