Dirty Thirty’s

Male testicles that range from the age of 30-39. These testicle tend to have problems, this is when men should get their sperm count checked and make sure they have a lively swimmers. If a male has a lack of ability to hold a woman, it must be because his balls don’t work. This is a common theme for people named Daniel. More than likely it has to to do with looks, but their testicles get saggy and sweaty throughout this 9 year period. Most women do not like a man with “Dirty 30’s”, especially those who do not get them checked out. Damage to the testicles may also expedite this process.

Person 1: Dan, you suck at dating!
Person 2: No I don’t! It’s women being women!

Person 1: Dan, it’s your dirty thirty’s! Most women and little girls don’t want that, they want Man Balls!
