Koi fishing 

When 2 people suck each other's toes 69 style. References those cliché koi pictures where each fish's mouth is by the other's tail.

Those freaks were caught koi fishing in the attic!

Koi Boy 

Someone who is a big fish in a small pond who thinks they're fancy but are really pretty basic.

Ex. That koi boy is always popping off.
Ex. That koi girl thinks her shit is high fashion when it's five and dime

koi be 

It means, 'Where are you?' in Bengali and often used among friends coz it's an informal way of speaking 'apni kothay achen?'

Koi Be? I've been waiting here for about 30 minutes.

Koi Vtuber 

She’s a fish made of many talents, she’s an artist, a singer, and she’s absolutely cracked at any video game she lays her hands on.

Koi Vtuber was the coolest fish in the sea.

A fish of many talents, she can draw, sing, and literally yell from the top of her lungs… maybe.

Koi-Boy

Koi-Boy play on words, Koi as the fish, a prison reference to new fresh meat. Also sounding as coy when people are being coy. not to be confused with someone’s bitch in prison, but rather communal property for everybody to exploit. an individual that entices and yet disgust the perpetrator because this person at least in their minds is enjoying being communal property and can’t get enough.

Hay look! Koi-Boy thinks he can hang!!! Everyone knows you’re just a Koi-Boy!!! You’re going down, in every way imaginable BITCH!!!

albino koi

A tampon left floating like a dead fish in the toilet, usually left by dirty tramps with no bathroom wastebasket.

My roomate Missy left me an albino koi in the toilet, boy it sure did taste salty!
