n. or v. Spidermining is when you let loose an especially noxious silent-but-deadly in the aisle of a store, then hurry away so that nobody who enters the aisle can tell that you were the one that dealt it. Named after an invisible weapon in StarCraft that is dropped from vechiles and explodes on impact with an unsuspecting unit that runs over it.
"You may want to stay away from hair care section. I just dropped a couple of spidermines over there!"
