When a guy has 6 pack abs and giant balls to match the abs. So that it looks like there is an extra pack down in the pants region.
tian: your cup is really showing
kenny: im not wearing a cup :D
me: how did you get an 8 pack?
kenny: i fucked a fairy and it granted me a wish
abs worked past a six pack. 8 packs have two aditional abdomanal muscles above a 6 pack making you look more ripped then your average 6 packers.
damn that kid's pretty ripped with that 8 pack hes got
