Six pack

From Frikipedia

Either:

1) Hunky abs. Impossible to get unless you are famous and therefore have nothing to do all day other than lie around doing crunches and being pep talked to by an overpaid personal trainer.

2) Mythical amount of beer cans. In England, cans are only available in 4 packs or 8 packs. Six packs are the middle of the road wussy American version. And their cans are half the size of ours. As opposed to their cans, which are usually twice the size of ours.
