langwing

Langwing is a mis-spelled version of the word language.

It was a running gag in episode 108 of the youtuber Jacksfilms series Your Grammar Sucks

It is used much in the same way as the "Watch your profanity" meme as in it can be used in a serious way and joking

Comment 1: You are is motherfucker

Comment 2: Yo watch your langwing

Jack: What the fudge

Bob: Yo watch your langwing
