A true gentleman. One of the last few of a dying breed. A humble motherfucker with a big-ass dick.
Hoe #1: Who is that sexy piece of ass?

Hoe #2: Oh, that's Boomer! Chicago's finest. 773 represent!

An annoying "special" zombie in Left 4 Dead 2. It's a fat-ass zombie that throws up on you, making your sight all loopsy like you're on an acid trip.
Man, Boomers are the worst!

Those who think they can drink a lot, end up drinking too much and puke their guts out resembling a boomer from the Left 4 Dead video games series where a boomer pukes on players.
Holy shit! I can't believe Brandon drank that much! He looked like a total boomer when he was puking his guts out!

A boomer is when a guy has anal sex with a woman and cums in her ass. Then the guy lays down while the woman squats over him. She proceeds to rip a huge fart, spraying his own shit-incorporated cum all over his face.
I payed this whore $50 and she rocked a boomer in my face. -OR- I can't believe I actually got my wife to boomer in my mouth.
