no backsies

Once a deal has been made, it has been made.

It can also be further interpreted to mean some transition into a new situation has taken place and there is no means for return.

Example 1: nah, we did a fair trade between your charizard and my pidgey. There's no backsies, gg.

Example 2: that christian girl is trying to pretend nothing happened, but I totally fucked her up the ass lol. There's no backsies.

Backside

Backside is the word used to describe when a guy has permission to enter in the alternative option. In general, all guys like to go up the backside but it's a true honor and gift.

Me: I've been dating Joe for six months, and I finally gave him a season pass to go up the backside.
Friend: Shit really? You must love this guy. Oww

Backside of the Poon

When you look at a ho from the back and see a little bit of pussy from the ass. And I’m not talking about the gardening tool.

When I told that bitch to make me some Chef Boyardee I couldn’t help but notice the backside of the poon.
