1. A blatant typo, during the execution of "lmao" the fingers are set upon the incorrect keys, in fact, one too many to the left, on the right hand. This results in "knai"

Often thought to be a typo of lmao, But what it really stands for is Kicking Nazi Ass Indoors. The term originated during the Holocaust when Nazi's would walk into jews homes and if someone called for them while they were fighting they would scream out "KNAI!!" Or when Jews wrote to each other they woudl often finish a letter with knai !
It is now used as online slang to say something is funny.
Barbara: Knai !
Alina: Ew ! you fucking retard learn to type !
Barbara: You learn to read dumbass, i said Knai, Kicking Nazi Ass Indoors !
Alina: . . . . . . . . Oh ?
Barbara: Mhhm and what bitch ?
Alina: :-(
Barbara: You just got Pwned Noob !
