Firend: I have something to tekll you.
Other Friend: What?
Friend: I'm a hobosexual.
Other Friend: WTF is that?
Friend: Ya know that guy that lives under that overpass by the mall?....
A person who has sex with anyone so they have a place to sleep at night.
He got evicted from his appartment so he is over there trying to hook up with that fat girl so he has a place to stay, you can't be anymore hobosexual than that.
