Rainbow Kissing 

When a person shoves a potato covered in pickle juice down their mouth then the other person fills Their mouth with mayo and ketchup then the people both start making out until the potato explodes in both mouths causing a vortex to destroy the whole world.

Little Tim don't you dare start rainbow kissing so we don't lose that thick potato.

Rainbow Party 

When a crowd of girls give one or more guys a blowjob wearing different color lipsticks. This causes the penis to have different shades on it, therefore making it look like a rainbow.

Note: Has nothing in particular to do with homosexual orientation (though it could)

Taylor wore red lipstick, Vicky wore orange, Sarah wore yellow, and Caroline wore green. They sucked intensely at the rainbow party, almost like a hoover. That was all I saw because the dick had cummed with those colors on it. I bet the other girls felt left out...

rainbow mafia

General name for individuals or groups who push the neoliberal LGBTQIA+ agenda aggressively and without room for questioning, critical thinking, or compromise. Dissenters are subject to ad-hominem attacks and online doxxing.

The rainbow mafia is always forcing people to accept anything trans… and if you do or say anything to dispute it, you're a villain.
