Let me fall into the koi pond 

The failure on a friend's part to step in and prevent a terrible situation from happening. In most instances, the friend not only fails to prevent the situation from happening, but makes an observable effort not to help. This is an allusion to The Office Episode where Jim leans back and allows Michael Scott to fall into a koi pond.

Dude I can't believe you didn't do anything back there. Way to let me fall into the koi pond, "friend"

Golden Koi 

A geeky looking dude who wears glasses and a beard, as well as a goofy hairstyle. This guy also tends to stutter and come up with weird playful insults. Typically dresses in clothes that do not match and he even walks like he's messed up in the head. He has a bad habit of blurting things out of no where. He never takes his head phones out of his ears, even to save his life.

Generally has good taste in music and video games, but not much else. Is addicted to television and movies. Is possibly a closeted homosexual. He also has violent tendencies and others must not let their guard down around him. Golden Koi can be a loveable guy, but also a major pain in the ass.

At the end of the day, Golden Koi is a human being and should be respected as such. Doesn't mean you have to kiss his ass, but simply be considerate of him, as you would be of anyone else.

Oh God. There comes ol' Golden Koi. This guy is fucking annoying sometimes.... Bless his heart.
