ass clock

A device similar to that of a clock except it is surgically emplanted into the cheek of your choice.

"Dude, I love the ass clock man."
"I know right ain't it sick? I can tell the time just by checking out my ass!"

ass o' clock

Really, really f-ing early.

Dude, I had to be up and out of there at ass o' clock in the morning.
