Similar to the high five or fist bump, Butting is a satiric trend involving two or more people bumping their bare butts together as a way to say hello.
1. I hate using the toilet immediately after someone else; we might as well be butting.
2. Hey, bro, will you take a pic of us butting, so we can post it all over the internet?
