Eternal bumflower 

A group of seven male friends begin a circle jerk on a rooftop in Southeast Asia. They simultaneously climax, then throw their legs back like synchronized swimmers forming a perfect star and tan their buttholes for 10 minutes.

Hey buds, don't miss the eternal bumflower this Sunday!

bumfloss

A G-string. A piece of underwear that has a thin strip of fabric that hides in the crack between the buttock cheeks, rather than covering that crack like normal underwear. Named for the similarity with dental floss, that cleans the cracks between teeth.
