Gokay

Used when informing someone that they have overstayed their welcome; simple way to tell someone to leave (can be used jokingly as well as seriously)

Thanks for coming over man, but, gokay?

Damn bitch, just gokay?

Lifen’t

When put into a combination with the right words, it can be used to tell someone to end their life, or inform them they have no life.

Go commit lifen’t.
