An enemy in the PC game Minecraft. Creepers are quiet and do not make any noises until they are very close to you. When they are next to you they will make a "Ssssss" sound, much like a fuse on a bomb, and then explode anything in your area, including you. If you kill them, they sometimes drop sulphur.
Damnit, that creeper blew up part of my house last night. Now I have to fill up the hole in my bedroom.
