Creepers is it just me or is that word used to much? The word creeper defined is A person who does weird things, like stares at you while you sleep, or looks at you for hours through a window. usually a close friend or relative. you know right away if that person is a creeper or does creeper things. it is not hard to spot the creeper. Is it ironic that creepers in minecraft seem to stare at you silent at night,like notch programmed AI into them?
