An unattractive woman with overly large (presumably fake) breasts who flaunts them for attention. Of significant importance to the "bowser" designation is the presence of a jacked-up face (too much botox, a dead tooth, a weird mole, leathery skin, etc.) with the pair of obnoxiously large, sometimes veiny or misshapen, breasts which are barely contained in a tank top that's a size too small anyway.

Dave: "Yeah. Bunch of fuckin' bowsers working that night."

A very ugly looking girl.

a SUPER quiet loner type of guy. never talks, even when he's with his group of the few friends he has. makes situations awkward with only his presence & when he does say something everybody listens. also has a distinct smirk when he smiles.
This Guy: Oh, hey, Bowser.

Bowser: ...

That Guy: Don't mind him, he doesn't say much.

While this is indeed the name of the bad dude from mario, this word is commonly used in New Zealand when referring to the object you use to smoke marijuana when having spots. Some merely call this the spotting bottle, we, however, are more inventive.
Hey man, pass the bowser you fiend
