A word used to describe a boring person. A person who would normally be down to have a good time, but for no good reason, decides to be lame on occasion, or often. Used mostly on occasions that involve social gatherings with a group of friends; getting stupid drunk, going to the football game, playing wingman.
Jake: Are you going to that 21-run tonight?

Mike: I don't know, I'm kinda tired.

Jake: Dude, it's 4 in the afternoon...

Mike: Yeah, I think I'm just gonna stay home and watch a movie.

Jake: (to a group of friends) Well Mike isn't coming out tonight, he's gonna watch a movie.

Crowd: Wow, what a nannywhomper.
