back in the day

something from the past, sometimes from one's younger years, or the beginning of something.

"I used to play some ball back in the day."
"That team was actually good back in the day."

Back in Three

To inquire about one's preference for anal sex in the third encounter(conversation) with said person. Then, to have anal sex shortly, thereafter. Immediately would be preferable, without any intermediate conversations. Male to male use of this is not condonned, but words are words, so if they adopt it, so be it, but this case is refering to guy to girl; girl to guy; or girl to girl. Unless, the male to male conversation is asking about the said male's preference for anal sex with other women, and no anal sex between the males must follow.

Todd: So are you gonna try to go through the backdoor with Jackie.
Derek: I've only spoken to her twice!
Todd: Bro, just pull a "Back in Three"

Back draft

When you’re getting your ass eaten doggy style and you fart into your partners mouth.

Bryan: I’d like to discuss what happened last night after that steamy episode of Grey’s Anatomy.”
Steve: “sorry, If I caught you off guard when you were rimming my behind. There’s nothing worse than back draft on a first date.”
