Short for weakly interacting massive particle.

WIMPs are considered by some scientists to be candidates for the dark matter that makes up much of the mass of the universe.

An ineffectual person; a soft, silly person; a weakling; drip, nebbish: Unmacho. Short hair, glasses, awkward, uncertain. WIMP/ his unfortunate and unfounded charge that Thompson portrayed him as a ''wimp''/ Apparently whimps complained it was too hot
