m.u.f.f.

M.U.F.F. - mandatory ugly friend. A hot girl who has a ugly usually large nosed vengeful aquaintance who no guy wants to touch.

If the girl is ugly enough the wingman won't even touch her. Then the cockblocking comes in.

man, her friend is hot but that big nosed m.u.f.f. is cockblocking again.

Can you take one for the team?
