Dude, do you always have to be so damn obnoxious? You're such a manboy!
Damnit, I get carded everywhere I go, Must be because I look like such a manboy.

Did you see those manboys knocking over those kids at the game store when Call of Duty was released?

Wow, that's a good-looking ManBoy!
I went to a show last week and I met a ManBoy there.

Like a sixteen-year-old, Manboy can’t be trusted with the simplest of domestic tasks, such as cleaning up after himself. Manboy is often seen checking out other women in front of his girlfriend or wife.

www.manboys.wordpress.com is a blog about manboys for more examples.

ManBoy is so stinky that his room now has absorbed his stink and stinks nearly as bad.
