A cretin; a moron; a complete and utter idiot. Name come's from the fact that their brain is mushy like sludge. May also be because they're so thick like sludge.

Occurs when the girl lays at the edge of the bed naked while the guy stands above her head (also naked) and quickly drops on her face causing her legs to shoot up paralell; the guy will then quickly grasp her legs pulling directly back causing him to be on bottom on a little thing they call 69.

I gave this girl the best sludgegammer last night, her lakes looked like rubber.

Greg, you shoulda seen me sludgeham this chick last night.
