As in buttocks.
I said it today as Sarge and I were getting into the car on the way to the gym. I was having panty issues, and he mentioned that he does not have that problem with his undies. And I said, "So the whities stay firmly in the cheek crease of your 'tocks?"
It's been a long time since I've been able to make him laugh that hard. I shall have to now use that word at least ten times a day.
Thank you Cuteoveload for my new favorite word.
Other than panty issues, nothing. My life is just that boring.
