back scrape 

The unfortunate circumstance that occurs when a male is receiving oral sex and the person giving the oral sex accidentally applies teeth to the man's penis. Typically, this occurs when the penis is exiting the giver's mouth, hence 'back' scrape.

Last night I hooked up with a chick and, when she was sucking my dick, I

was the victim of some unfortunate back scrape.

Scraping the shit off my back 

To wipe away one's daily hassles.

The other day I had a blast scraping the shit off my back while listening to ASMR in my bathtub.

backscrapalating 

Continuing to live in illusion when you know the truth.

Short version: backscraping

It feels like I'm backscrapalating. I just know my partner is cheating on me but I can't admit it to myself.
