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!"
Ann and Curt 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

When two bro's (usually frat boys) reach between their legs to give bumps. Bibye bumps are usually reserved for saying farewell to your most intimate of bros. Bibye bumps can be done back to back, front to front, or back to front.
