Mip is the male version of a nip, where as when a woman, most likely a celebrity, has a nip slip, a guy would have a mip slip. Usually occurs with guys that like to wear open shirts or fishnet shirts.
"Hey, check out the flamer with the fishnet shirt. He just had a mip slip, and he doesn't even know it."
