Coco Bump

A sexual act performed by locals from several caribbean nations with visiting female tourists, always with their enthusiastic consent. The female holds onto a buoy, log or other bouyant object in the ocean, while being simultaneously penetrated anally and vaginally, by two males. To people on the shore, it merely looks like three people swimming in the ocean and is thus a very discreet sex act. Known in Jamaica, Aruba, Bahamas, Trinidad and Tobago, St. Kitts, Nevis, Barbados and U.S. Virgin Islands.

My ex-girlfriend went with her girlfriends to Hedonism II last summer. I later found out she did the coco bump with some locals and summarily dumped her.

Coopa Bump

This is a game that applies to Mini Coopers. Just as you would punch a friend's arms after seeing a Beetle Volkswagen car while saying "Punch Buggy yellow, no punch back", you would BUMP your arm into your friend's arm while saying "Coopa bump green, no bump back! if you see a Mini Cooper car" (Google it if you don't know what kind of car that is)

The same rule applies:

-You say license to avoid one mini cooper
-You have to say "no bump back" to avoid your friend viciously bumping you back
-Just have good ol' fun attacking your buddies and annoying siblings

This game was created by a competitive couple (A & C) who need more than Punch Buggies to win against each other in their games. See Vespa as well.

"Coopa bump (color of the car), no bump back!"

Elle and Tee are walking down the street one sunny morning. Suddenly, Ann sees a black mini cooper driving down the block. She bumped into his arm, shouting"Coopa bump black, no bump back!"
Curt: Aw, man you got me again.

Ann wins again for the day
