Get the Uniboobmug. Having been born with only boob.Commonly referred to as "Lost Boobage",Girls with only one boob are likely to have a G--or atleast a D cup size.To men,they're less attractive,like julia roberts.There's been a couple men uniboobs,but its only like 1 in 3 dudes who have "Uniboobs".Charlie sheen is one of them,how else did he scare that male hooker?I mean,think about it,they're like cheerleaders!

Get the Uniboobmug. When a woman's boobs look like one. Also, two boobs combined with more than 2 nipples, so like maybe 8 little nipples all over the Uniboob.
