The female equivalent of the cock block, but amongst two girls who'd like to get it on. A much more graphic term to use than box lock.
Trent is hanging out with a bunch of his lesbian friends at a bar. One of his friends' name is Lily.
Lily: That girl at the bar is so hot. I'm going to go hit on her.
Trent: No, I'm cranky. Let's go home.
Lily: Ok fine.
Trent has just clam jammed Lily.

The last Saturday before finals at Fairfield University in which thousands of students flee the overbearing pigs that run security at school and migrate to fairfield beach for a fun filled day of binge drinking, bitches, and beriut. Clam Jam includes various bands, dj's, drunk security guards and of course plenty kegs to go around.
It has recently come under the scrutiny of full time residents at fairfield beach who bought beach houses in a college town for half the price, expecting no disturbances. As much as these fun suckers try to ruin our time, clam jam will always live on.

With a variety of clam, from the Bearded Clam to the Soft Shell Smooth Clam, many Clams can be found with Clam Jam. Clam Jam is a buildup of male ejaculation, that becomes engulfed in the clams natural frothy excretion, causing both to solidify into Clam Jam. Clam Jam can be identified on these Clams based on texture, and jello like texture. This makes for a wholesome snack on crackers when obtained freshly from the Clam. Most Women quite enjoy the Clam Jam spread on crackers with a cold glass of pink Moscato.
