Rainbow Trout 

A poop that is so big and so long that parts of it are sticking out of the water in the toilet bowl and are changing color due to oxidation.

Garrup hasnt pooped in 4 days, but today he finally made a rainbow trout and feels relieved.

rainbow jackson

Rainbow Jackson is the most beautiful lightskin girl in the world though she doesn’t know it many adore and look up to her. She plays very hard to get and you can never tell if she actually likes you or not but if she does then you’re lucky.

Did you see Rainbow Jackson today?!
