GMG 

Gooning Munting Gang - an abbreviation of internet slang terms that can be used as endearment or disapproval. Also a play on the words gng (meaning gang). Asking if someone is GMG can be seen as asking if they are 'down with the kids'. Saying "This is so GMG" is ironic, and can be used to display disapproval or dislike toward an action, event, person, object, etc.

"Why would you do that? Are you even GMG bro?"
"Man, my mom was just in a car accident - ts so GMG💔"

gmg 

It means "grind(s) my gears" which is an alternative expression for "pmo" (piss(es) me off).
It was invented on the social media platform Instagram and is used as a replacement for pmo because pmo got used too often.

He: I like school.
Me: You gmg bro.
