buttwumpus 

n. A person SO lazy, they think having fun takes too much effort to be worth it. Buttwumpi can't even be bothered to play video games or channel surf. Surprisingly, most are thin, as unlike couch potatoes, they are too lazy to eat much.

"You can 'just sit there' at the club, too, but at least there you'll get a lap dance while you're at it! Don't be such a buttwumpus!"

butthumper 

Immune to the laws of physics and incapable of independent activity, the butthumper finds your rear bumper on an open stretch of highway, and stays there. The asshole may be using you as a shield against radar, or as a fuel-mileage aid, but usually he/she is talking on the phone and relying on you to scan the road for them.

Ten lanes of superhighway to drive on and this jerk has to tailgate me. What a butthumper.
