lug(redirected from a lug)
slang A large, strong, typically bumbling or foolish person, especially a man. Sometimes used endearingly. You wouldn't be acting so cocky if that lug weren't here to back you up. Ah, come here and give me a hug, you big lug!
n. a stupid male. (Possibly akin to the sense of “pull” = one who pulls or drags something as a laborer.) Is this lug bothering you, lady?
