Butt Crack, as termed by Wikipedia, is called the intergluteal cleft, also known as the natal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, so named because it forms the visible border between the external rounded protrusions of the Gluteus maximus muscles. The intergluteal cleft is located directly above the anus. Yes, it's called butt crack!
Despite who you are and what's your status, we try our best from falling into style blunders. Whether it may be a planned disclosure or an accidental mishap, butt cleavage is a common mistake.
While I was having dinner yesterday, I can't help but notice the most heinous, awkward, and impossible-to-forget butt crack right before my meal. It's kinda wanting to tell me, what goes in from the top, is gonna have a hard time popping out down there. Go get yourself a decent piece of underwear dude!
