cock o'clock
when you get off work and your woman is waiting at home for you to hit it.
Bikel heard the five o'clock whistle and he knew he had some sweet, sweet lovin waiting at home for him. It was his cock o'clock.
cock o'clock
The time of day that arrives when you show up at a bar or house party, and there's barely a chick in sight, except maybe a few fugly ones, and you have to leave and go somewhere where it's not a total sausagefest.
"Bad news boys, it's cock o'clock in here. We're gonna have to split and change locales if we want to sink the pink tonight."
cock block o'clock
That moment when someone or something prevents you getting laid.
We better hurry up and fuck! My roommate is due home soon and it will be cock block o'clock.
COCK-SLOP O'CLOCK A DOOOOOOO
When your girl wakes you up before sunrise for a lil sexy time, specifically a blow job.
Man, I was trying to sleep in but my gf woke me up at 6am shouting like a rooster, "COCK-SLOP O'CLOCK A DOOOOOOO!!" and then just started going down on me. Weird, but sometimes you just don't question it.
