Bum Scrubbing

The act of rubbing butt cheeks to make a slapping noise with your business partner in a shower.

Ah yes, that bum scrubbing session really helped us set our quarterly business goals.

butt bum

It's a poor person (bum), that takes (scabs) the last bit off the cigarette (butt) with a tiny bit of tobacco left in it that people usually drop on the ground once they are done with it.

''Ah man, got to work for the rest of the week and i'm broke as hell, i might have to be a butt bum for the week''

bum technology

Any sort of tool, shelter, or device crafted from materials easily accessible to the homeless by a homeless person. An example would be a bench press constructed from two wooden crates, a slab of plywood, some rusty bike frames, and a large metal rod fitted with bags of sand or cinderblocks on either end.

"Is that homeless guy fishing with a stick and some pipe cleaners?"

"Yep. That's some serious bum technology"

Bum-comfortable

For men or women: When going out in public and not wanting to dress appropriately due to desiring comfort over style and not caring what anyone thinks -- dressing down in one's at-home comfy clothes. Not shaving, etc. Looking like you just woke up, a bum.

Hey, let's go out tonight? Ok! But I'm dressing Bum-comfortable, like it or not!
