One Pack

Quite the same as a six pack. One giant ab covering all the others. they're in there no doubt. just... hiding. A common excuse for chubby people.

- a one pack is easier to keep track of.

one-pack

A large protusion eminating from the midsection of a portly individual. A fatty's gut. Much like the six-pack but without all of the tone. Also refered to as the fuel tank for the love machine and the roof over the meat house.

Though Hank thought of himself as fit, his one-pack shot that all to hell.

One Short of A Six Pack 

A term used to describe a person who is not all there. A person missing a marble or two - a few percentages off from being full blown retarded.

"I can't believe that guy just walked into that glass door - what is he...one short of a six pack?"
