A Spam is when you smack a guy on the forehead with a flat hand or preferably a fish while shouting Spam.

Can be played as a Spam war, which is a version of Uncle but with spamming.
Random Guy: Spam!

A Random Spaztard: Oww! Now i'll tell my mommy!


Random Guy: Spam War!!!
Random Guy's Friend: I'm never gonna say uncle!
1 Minute Later...
Random Guy's Friend: UNCLE!!!

2) An unsolicited and usually annoying email usually reserved for advertising.
3) Gaming #1: the overuse of any weapon (i.e. grenades, rocket launchers, etc.)
4) Gaming #2: in RTS (real time strategy) games, to mass produce a certain unit (usually only one or two--especially used with over powered weapons) to use in a quick, game-winning assault.
I really hate playing against John--he does nothing but sit back in his base (often called turtling) and spam out two dozen tanks that kills anything in their path.
