condition in which instead of having two testicles a man, they're so small that they appear like they only have one. which is usually an insult if you hear a girl talking about her boyfriend's uniball
p1: dude, tim is so hot!
p2: yeah he is....but i heard from katrina that he has a major uniball situation goin on
p1: *gags* oh snap. never mind then
