mmgn 

(making machine gun noise)

Similar to lol or rofl. Originates from Taylor Moore's laugh. When something is utterly hilarious her tongue rolls against the roof of her mouth, creating a sound similar to machine gun fire.

"Did you hear about the new pirate movie? It's rated arh!"

"Oh, mmgn! That's hilarious!"
