Some people believe a molooly to be a stupid ape like creature which lays eggs, in truth a molooly is a plain old oaf with the appearance of an ape, the rumours about the molooly actually existing got out of hand. A molooly is usually used to describe something that is either obese/gay or for some reason egg shaped in a comical fashion. Someone who takes a long time to respond due to idiocy is often referred as a molooly.
Hey, I saw a fat gay man.....he looked like a molooly.
Why dont you answer me? You are as slow to respond/react as a molooly!
