Lumb is a famous homo-erotic acronym standing for: Lube up my butt.

It can take on two meanings. It can be a command, dictating one's gaysexual boyfriend to lubricate one's asshole, or a state-of-being, such as in the example shown below.
I woke up with oodles of lumb.

Carl, for fuck's sake, just lumb!

The opposite of grool (as used in the beloved film Mean Girls). To be lumb is to be lame and dumb all at once. Can be used as an adjective, noun, or verb.
Jack: Nicolas Cage used to be grool, but everything went downhill after National Treasure 2.
Ash: Yeah, now he's just a lumb actor.

Jack: Don't be a lumbdog millionaire.
Ash: Yeah, don't be lumb and lumber.

Annabelle: This little lumb of mine, I'm gonna let it shine!
