6:9 

Pronounced "6 outta 9" A sex position similar to the 69, except that each partner defecates into the other's mouth. Common sense would dictate that each dot represents a turd being consumed by one of the partners, but the position is represented as such do to the 6 and 9 being separated by a colon, a clever play on words as well as poignant symbolism.

"Can you believe I have to pay an escort $1200 for a 6:9 these days?"
