Grand canyon yodel 

When a person inserts their nose into the other persons anus, then puts the ballsack into their mouth, yodels into beautiful harmony thus creating vibration on the lucky man's testicles, then blows their nose into the persons butthole.

I love giving Grand Canyon yodels in the Simon Kenton restops.

grand canyon ass

wide ass with a deep, long crack. most likely a result of too much ass ramming

Her grand canyon ass was so big and wide, when I tried to hit it from behind, it sucked me in like a black hole
