budlust 

that urge to take another hit even though you told yourself earlier that you didn't wanna get that high.

Developing budlust:

"Hey guys, I can't smoke too much today, I have a job interview in an hour..."
5 minutes later: "One more hit couldn't hurt..." ;)

bumdust

The brown dust that falls from the bottom of someone who doesn't wipe properly. It's the dust of dried-up feces.

Have you seen Lee's bumdust? It falls all over the place. They really need to learn to wipe properly.
