cumbacker 

A woman who has sexual intercourse which concludes with ejaculation on her back side. Usually as a sign of disrespect and/or due to cosmetic defects on the front side of one's body (i.e. the face or breasts), cumbacker is often used as an ironic pun as the male will rarely come back once he is spent.

Sally knew she was a cumbacker when Johnny ejaculated onto her back and left without saying good-bye.

Cumback 

A quick reply or retort where one distorts a seemingly normal conversation into a dirty one with a sexual partner or interest. The dirtier the better.

That’s what she said would be considered the most simple form of a cumback. Of course, the more unique and specific the response, the better.

Him: Hey wanna hang out?

Her: What time?

Him: I’m off work at 9.

Him: Lol I have a long meeting tomorrow so I’m probably gonna be drained around 9 or 10. Next week?

Him: I know something else that’ll be drained around 9 or 10... inches

Her: Ugh you’re right, let’s fuck!

Friend 1: You always gotta hittem with a cumback

Friend 2: Why’s that??

Friend 1: Because talking dirty and suggestive makes her think of you... sexually. She’ll be thinking of the dick! Plus it’s entertaining. For everyone involved.

Friend 2: Even with mediocre dick?

Friend 1: Even with mediocre dick.
