A form of "dancing" used by pre-pubescent scenesters and older emo/scene eunuchs alike. These people are not true music fans, they go to shows to be seen by their friends. This display of jackassery annoys the piss out of true fans, who end up beating the scenesters to bloody pulps between sets. These kids don't have the nuts to mosh.
At the Dream Theater/Opeth/3/Between the Buried and Me concert yesterday, the mosh pit started when some asswipe's slam dancing connected with a Dream Theater fan. The true fans around beat the slam dancers down mercilessly.

A type of action done by kids who are too weak to get into a real mosh pit so they must pretend fight so they won't get knocked on their asses.

What hardcore and some emo kids do when they go to metal shows. It consists of randomly swinging their arms and kicking in random directions. The point of these people is so that true metalheads have a reason to be pissed off and therefore mosh harder. A new game has arisen in the metal scene called "Who owns slam dancers the hardest."

To slam a trunk shut in an inappropriately firm fashion in order to demonstrate one's disgust surrounding their poor performance on the golf course that particular day. Trunk slamming most often occurs when (A) a player has missed a cut and is rushing to catch a flight home, or (B) When he/she played well below their potential and are in a hurry to get to the bar.
Mark was yelling fore-left all afternoon and lipped a 3-footer for triple on 18, so now he's out in the parking lot trunk slamming the afternoon away until happy hour starts at the airport.

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.
