back shark

Derived from Jamaican slang. Much like the United States uses “69” as a way to symbolize dual-action oral sex, Jamaicans use the last two digits of their year of independence (1962) to depict the act of a a man slamming a woman from behind, whilst pulling her hair back, much like grabbing the dorsal fin of a shark from behind and pulling.

The term is also used in the popular game “bingo” when one cries out after matching 5 numbers. Essentially, meaning one has “nailed it!”

I took her home last night and delivered a brutal shark back-ing. That’s why she’s in a wheelchair now, Maahn.

Janet covered her last number, stood up, and yelled “back shark!” to claim her prize; a large gold pendant in the shape of “62”, and the resort staff have noticed.
