Poutine Fries is slang for ejaculating onto feces that was released
accidentally following an emphatic bout of anal sex. Specifically, as the male pulls out and is about to release, the recipient's bowels accidentally begin to move. However, as the male has already begun to ejaculate, the result is semen-covered feces. This is said to resemble poutine fries, the
French Canadian dish of
French Fries covered in gravy and mayonnaise.
