Have crept into straight culture so couples can have sex in public places - elevators, subways, etc.
Pants usually have some easy way to attach the two flaps on material: buttons, velcro, string - no zipper. Underwear is not worn - but can be for more 'fun'. If vice squad in club, lack of secure attachment allows aliby - i.e. dancing so hard pants can apart. etc.
Jane - WOW! Sweet boner pants Jack!
Jack - Yea, they are sweet. Too bad I have one testicle.
Jane - I like to punch babies.
Justin: No, im being emo for halloween
Ben: yah but there bonerpants
Justin: well at least im not wearing a bra
This can lead to some pretty embarrassing experiences.
Son (blushing, covering pants with shirt): Yes mom... uh, they sure are.
