Croc-five
The "Croc-five" refers to when two mutuals with the same pair of crocs celebrate their similar choice of footwear by removing said crocs from their feet (adjust sport mode to leisure if needed), place left shoe upon left hand, right shoe on right hand, then high school musical style jump in the air, bend knees slightly to achieve maximum distance from the ground, and double high five your partner with a photo-magic smile.
"yo bro, we be rockin' the same pair of crocs! you know what that means... Croc-five!!!!!!"
