A Pi Lam slam is in reference to the fraternity: Pi Lambda Phi.

It is a noun used to refer to a girl that has slept with AT LEAST 4 members of Pi Lambda Phi. Some will stop at 3 just to avoid the bestowment of the term, in which case they may be referred to as "one to go".
Brodysseus: Hey man, how far off is Cindy?

Brochacho: One more to go as of last night.

Brodysseus: Inching close to the Pi Lam Slam, haha.
