Top Definition
A collection of songs, usually an iTunes or iPod playlist for the sole purpose of "setting the mood" before and during makeout/sex sessions.

Slam Jams, which are particularly popular in college dorm life (to drown out noise for eavesdropping roommates), are usually comprised of an ensemble of smooth R&B tracks, including artists such as R. Kelly, Bone Thugs n' Harmony, and John Legend, to name just a few. However, many have adopted acoustic indie rock (ie. Pete Yorn, Nick Drake, Elliot Smith), 80's (The Cure, Cyndi Lauper, Foreigner), and electronic music (Tiesto, Kaskade, Robbie Rivera) as their Slam Jams of choice.

Regardless, it is always recommended to have at least 3 solid hours of Slam Jams ready BEFORE you bring your mate back to your place of residence.
I couldn't sleep at all last night! I woke up at 4 o' clock in the fucking morning to R Kelly - Bump N Grind coming through the goddamn walls! Can Maurice get some new fuckin Slam Jams already?

A drinking game in which any number of merrymakers attempt to bounce ping pong balls off a wall or window in to 4 personal beer cups while listening to "Space Jam" by Quad City Djs. Each player has 4 of their own cups that they must sink, drink and flip, in order to win. After a player sinks a cup, they must flip the cup from the edge of the table (like flip cup) in order to continue shooting at their remaining cups. The first person to sink, drink and flip their cups is crowned winner (and most drunk). The method of shooting differs from beer pong in that all shots must go directly off the wall in to each cup, making it a genuine slam jam.
Kris! There's a Slam Jam going on...what the fuck are you doing!?

Mandatory slamming of a full beer by all comrades who are drinking. The goal being to be the first one done so you can call everyone else a pussy.
After finally getting some beer, everyone grabbed one and I announced Slam Jam! All bottles were hoisted up with mine being the first emptied.

The party friendly short version is "Mandatory SJ"
