Ricky's mom was from Montana, and boy did she take my boat down her salmon canyon. Tell ya, she got wet and smelled like fish.

Evil Knievel's famous jump that broke him. In honor of his baddassness (also a word), Snake River canyon is when you gape a girls asshole and dangle your penis in it while shaking it like a wriggling snake.
I went to April's place last night, and after sperm whaleing in her back door, I gave her a Snake River Canyon for an encore!!
