Back on the D 

When a bisexual female changes her primary sexual interest from from female back to male and jumps from pussy back to the cock.

Hey did you hear about Rachel? She’s back on the D. Imma hit that shit before she changes her mind again.

knocking on the back door 

Pressing the tip of one's erect penis against a woman's anus in the hope that she'll agree to anal sex. This technique is futile 99.753% of the time, but persists due to the collective male delusion that women secretly love to be invaded in this way.

Boyfriend: (knocking on the back door)

Girlfriend: How many times do I have to tell you??? Get that thing away from there!!!

knocking on the back door 

During anal sex, the person that is doing the penetrating and thrusting is the one that is doing the "knocking," and the anal opening is, obviously, referred to as the "back door."

When Eric and Amy are in bed, he's always knocking at the back door.
