Bonker - A Bonker is a moderately attractive, charming, "girl-next-door" type female who flirts with every male in the vicinity without ever actually dating or hitting anyone. A modern derivative of the Siren, if you will. Rare exceptions can be made in odd cases of a male who is either too young or too old, chosen seemingly at random.
TITS! I thought shit was goin down with this one smokin asian girl in my apartment but it turns out she's just a total class-five Bonker.
A derogatory term, normally used by a group of gentleman to describe a rather promiscuous, somewhat deranged lady who isn't particular about whom she lays with in order to heighten self-esteem
