When a guy/girl is clearly blowing you off (has an excuse ready whenever you wanna hang out),but refuses to actually tell you he/she doesn't "like you like that" to avoid being the bad guy. Instead continuing to lead you on and assure you of how much they do like you and what an amazing person you are.
"He blew you off again? I think you should just give up on him...he's totally Bo'ing you."
the act of falsely representing yourself as a homeless person (see hobo) in order to garner or fulfill sexual gratification, accomplished by refusing to bathe for several weeks, raiding the goodwill donation box, and stealing a shopping cart from your local grocery store and filling it with discarded aluminum cans...and proceeding to rub one's self upon as many random strangers as possible till orgasm is achieved.
"Sorry, Bill, I can't go to the sports club with you tonight, me and John are going bo'ing in the red light district."
