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 Mouth

When, during oral sex, the penis only reaches the back of the mouth & doesn't ever enter the throat. This could be due to the penis being too short or the girl refusing to take it deeper.

"She's terrible at blow jobs... She tried to give me head, but she refused to deep throat me, I got some 'back mouth' at best!"
