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.

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