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..." ;)

Bumlust 

To have a sexual urge to grab the posterior of another individual.

As he climbed the mountain , he was overcome by bumlust of the person ahead of him.
