When you are drinking in the garage and decide to pull out some nudes of your girlfriend from the 70’s to show your buddies forgetting that there is one of you with your hands on your waist at full mast hence getting you the nickname “bonerman”
One or many guys running around chasing a hottie with thier raging hard ons in thier hands. Similar to a big concert frenzy or event only named bonermania
a typical person until they get 4 beers in their system. Then they turn into a zombie that will creep out the whole room and want your brains. Doesn't feel emotion and whose body moves slowly towards woman that don't want him near.
Typical conversation about a Bokerman:
guy 1: Oh shit looks like we got ourselves a Bokermann
guy 2: Yeah he hasn't said a word in an hour and he keeps staring at that chick
