He's probably been the butt of a few jokes.

TBone said the cause of his condition stems from pilonidal cysts, which the Mayo Clinic defines as, "abnormal pocket[s] in the skin that usually contain hair and skin debris." They are "almost always located near the tailbone at the top of the cleft of the buttocks."
As Tbone explained:
This happened because of severe pilonidal cysts. I've had multiple surgeries on it, and instead of the usual procedure which involves letting it heal, mine was so bad that a plastic surgeon had to close it up. But they keep coming back, and it'll probably just get worse as I age.
He also answered several other obvi-ass questions:
My butthole looks the same as anyone else's! The wound just goes very close to it. Trust me, you don't want to see it. Second, I poop like anyone else. Just gotta be careful with wiping so I don't get feces in the wound. But it isn't hard after having to do it for 8 years now.
He's also learned to come to grips with his condition.
"I used to be upset about the situation, but I've started to laugh about it, and I realized it's what makes me who I am,” he wrote. “Might as well laugh about it, right?”
