Just a guess, but I don’t think us men have much control over the size of our sacks.
Probably just another new fad that we'll have to endure: the peek-a-boo sack or some such nonsense. Probably complete with tattoos.
LOL! I think it's time for bed.....
In Washington all the politician sacks are empty, just a pouch of useless hanging skin. Some of the republican womens clank when they walk. :O)
