A pathetic person that sees conspiracy behind every post in Craigslist's Rants and Raves. A Thumper believes all posts that offend him are the work of one person. He also thinks that all flagging is done by that same person. A Thumper posts repeatably, with a complete lack of creativity, desperately trying to rally the troops to the validity of his twisted view of reality. He fancies himself as a leader, but alas has no followers.
The Thumper in WDC Rants and Raves is crusading against OBAMANAZI, a mythical person that exists only in his mind.

Thumper is a drinking game. How to play - everyone playing the game must drum their hands on the table/thighs/whatever you got and the first person to start yells out the phrase, "What's the name of the game?" and then everyone else yells back, "Thumper!" then the first person yells out, "And why do we play?" which is returned with, "To get fucked up!" then when all the drumming has commenced the first player does two dance moves then looks to a random player and then they copy the first players second move and then add a move of their own and then look to a different player and they copy the second players move and so on and so forth. If a person messes up a move then, that's when the drinking comes in. He/She has to chug a cup of beer.
"Holy crap, what happened to you last night?"

"Someone suggested Thumper. I was already too fucked up to argue."

A person who is either closeted or does not yet know they are gay. Called a thumper because they are in the closet and banging on the door to get out.
Bill is such a thumper! If you listen closely, you can hear the hinges rattling on his closet door.
