A person of unpleasant appearance (and usually odor) who does not neccesarily use crack cocaine, or any drug for that matter. Not to be confused with the home less or street crazies. A shopping cart excludes the person from being a crack bum if it is not filled with copper or other recyclable materials. Crack bums are usually spotted in populated business areas where there are few police officers. They are known for panhandling and mooching off of anyone they are acquainted with.(not the same thing as hippies, they have dreadlocks or pachuli) Having a home or at least a legal address does not exclude a person from being a crack bum.
Who is that dued bumming cigarettes and beers at the BBQ? I saw him the other day in front of 7-eleven wearing purple sweat pants and fake gators. He had a suede fedora from 1976. What a friggin crack bum.

To un-intentionally show you bum. Usually only the top part is revealed when bending down. Or if you’re a builder of some description you will already be wearing loosely fitting pants that assist in revealing your bum crack.
I was walking along the street when I saw two moons looking at me. The fattest builder was showing every one his bum crack. To which I shouted out say no to crack!

When you're outside having sex and you're ass is facing the wind and the wind blows up your arse a bit. Like if you part your arse a bit it'll get wind up it.
Y'know when you're at the park and you get wind up your bum crack just at the wrong time and your whole body shrivels up into a little raisin and you pull this face...
