Rainbow Ass

Any person that when they bend over has hair coming out of their butt. Referred to as a "rainbow ass" because it is popping out as rainbows do from clouds.

"Look at that guys rainbow ass,no one wants one of those."

ass rainbow

Shoot rainbows out of my ass

Extreme happiness beyond comprehension.

I'd like to meet new people (in person) and increase my social circles. If something clicks I'd like to get to know that person better in the name of dating. Eventually find eternal happiness and shoot rainbows out of my ass as I ride around on my unicorn for the rest of my life.
