The female version of a cockblock; When a female blocks another female friend from scoring a cute boy, due to jealousy or anger.
(Jane was talking to a cute boy at a party when her friend Karen walks up)
Karen: "Okay Jane it's time to go, I have to go home and feed my cat."
Jane: "Aww Karen quit being such a clam jam!"
Karen: "Okay Jane it's time to go, I have to go home and feed my cat."
Jane: "Aww Karen quit being such a clam jam!"

The female equivalent of the cock block, but amongst two girls who would 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.
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.
