"I was going to hit that until she saw my nub chub."
A nubchub is a short fat thing or person. It is similar to a stub, which is a lump, except round on top and flat on bottom, like a cylinder but round on top. Nubchubs are fatter than nubs or stubs. Nubchubs are also considered short fat people, under 5'6" and over 250lbs.
