mm'ing 

The act of fouling up an internet forum by posing useless hypotheticals, drudging up dormant shitstorms and posting innumerable polls with no conceivable purpose, merely to see your name in lights.

eugene: "What the hell happened to this forum?! It's like half of you are are mm'ing."

mm: "Poll: do you think this forum has gone downhill since my increased presence here, or not? Or does it not matter in the least? In any case, please respond. Or not."
