Log Jammer 

It's a water-ride at Magic Mountain in Valencia, CA.

Johnny: Hey Bobby, this heat is killing me... after the girls get out of the restroom let's go on the Log Jammer.

Bobby: No way Johnny, let's take 'em on Jet Stream. It has a tunnel which is a perfect place to grope their boobies.

Johnny: Good call.

Log Jammer 

When doing a girl from behind while she is hand-cuffed to the toliet Boondock Saints style, you shove your cock in her ass, dunk her head in the toliet and give her a swirly.

So I gave Heather a ride on the Log Jammer last week, she hasn't talked to me in since.

log jammer 

When one shits into anothers asshole, and the same shit is returned to the owners asshole. The shit is passed back and forth between assholes... Much like a sort of "hot potato" game.

James and Eddie did the Log Jammer! I walked in and saw them!!
