Used by BK to insult someone. When someone does something wrong you call them a bum. Can also be used in the context of joking for when they are being an "idiot" or a goof. Also can be used as a filler if you do not know what to say.
Person 1: can you help me with this?
Person 2: sorry. can't i'm to lazy.
Person 1: Your being such a bum.

Taking it up the dirtbox for sexual kicks, usually with a group of masturbating masked men looking on and stroking their meat!
"I was wondering what I could do to warm up my rectum on these chilly gay Autumn evenings and why, what better activity could I think of than calling up the boys and having them come round for a spot of bumming? They were at it for hours until my poor old butt was red raw. This morning I had to put on an adult diaper because I couldn't keep the shit up my arse such was the fun I'd had yesterday evening. Being gay is such fun. I love bumming!"
