Macktics
To flee and act in a cowardly manner in a video game particularly as death approaches; most notable in Super Smash Bros. Melee and Super Smash Bros Brawl. Can be used elsewhere with decreased effectiveness. Users beware of backfiring; other players may seek to single you out for your cowardice. Asshole. 
In Super Smash Bros Melee, suppose we have a Mewtwo, a Mario, a Ness, and a Falco. For some reason, Mario players are notorious for their Macktics. Mario is on his last life, and the other characters still have three or four. Mario runs and whores items in an attempt to gain cheap kills while truly skilled players duke it out in a true Smash Battle. The other players grow angry at this Macktic, and they all cease fighting to gang up on that Macktic whore.
