butt cheek kisses is showing your woman how special she is and how much you love her AND you will do anything to prove your love and total devotion to her.
To slide a "rod" between two spink cheeks and pumping it back and forth until climax is reached. (without actually penetrating the colossus cages of brown town)
"Sir, may I use butt cheek sex on your daughter, so that she remainsa virgin until marriage"

The girl I was out with last night, had such a nice bubble butt and she let me butt cheek fuck her in bed.

Social Butt-cheeking
The act of two individuals passing each other in a cramped space back-to-back rather than front-to-front or front-to-back.
Man: The aisles in that plane were so tight we needed to practice social butt-cheeking.
