Koi 

A super kind person who is charming, open-minded and full of love. To have a Koi in your life is to have a friend you know will always be there for you. She is a darling and a person you can always trust.

Get yourself a Koi my dude. She's what you need.

Koi 

The greatest friend out there. Always understanding and loving towards their closest people - helping with whatever they can.

Might struggle with self-expression and self-worth, therefore closed-off.

He usually stands out in a crowd. Mysterious demeanor.

Person 1: Who is that over there???
Person 2: That is Koi! Isn't he so cool!

Koi 

oh boy! Koi’s are girls that you will love! They are adorable and cute. They have a lot of friends but they don’t trust everyone around them. They keep the ones they want close to them and let go the ones they don’t want or not close to. Some are really sporty. Play most common sports. They are so goofy and laugh a lot they are smart and talented. They show who they really are and who they really are. If you find a koi it’s a pleasure to have her. She is different and stand out in the crowd. Follow her dreams and don’t let no one get in the way of it.

Boy1: hey what did you do today?

Boy2: I met this koi. She is really different out of all of the girls I met.

Boy1: oh wow I wish I met someone that sounds so good like her.

Koi 

A Koi is someone who exceeds far beyond the pinnacle of being a simp.
Someone who is Koi will give their partner everything, they will do anything possible for any sort of attention, in which most cases are virtual.

The Koi is also someone who cannot fight back, but far more superior then simp, as a simp would run away and leave the girl to her own death, but a Koi will pretend no one else in the world exists except the partner.

A Koi will most likely enjoy constant sexual behaviour and or entering furry type behaviour.

*in the video game of vrchat*
Koi: "I love you so much you mean the world to me"
Her: "You do too"
*they are both lying down virtually, she is a little girl character bouncing up and down on his virtual wolf furry characters penis*
Random: "Ew, stop being a simp idiot"
*Koi mutes the Random so he cannot hear the Random yell at him, but can say what he likes without consequence as the random can still hear him*
Koi: "You are a di*k and no one loves you haaha"
Girl: "You are so smart and cool *hehe*"
Random: "Jesus... You are such a Koi"

koi 

A sigh of exasperation, apathy, happiness or really any emotion. Can be seen as an exaggerated form of "K". The use of ka as a suffix can be used to indicate the degree of apathy.

Peter: Hey Kevin, do you wanna come over to my place and study for our english exam?
