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”
I went to a rager at Johns last night and saw a picture of his of his boner man... “bonerman”
A party where you run wild through the house with a hardon in your hand
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
