MNG

A file type one would _think_ makes animated GIFs nearly obsolete, but instead doesn't have much support.

MNG barely has any support, and isn't very well known. It's a shame, really.

MNG

A large, ugly pimple that develops on the ass if you haven't been washing for a while. It doesn't hunt, but will otherwise annoy until finally popped (usually with fire). If you don't continue to wash, it'll come back in six weeks.

Person 1: Dude, my ass is annoying the fuck outta me.

Person 2: I think you got an MNG on your ass. You should pop that shit and start washing your ass, you greasy motherfucker.

MNG Rämibühl

Worst best school in switzerland. Only school where you'll find more students playing cards rather than checking their phones during the breaks. Outsiders and administration think it's an elite school (which it really isn't).

"I went to the MNG Rämibühl in Zürich."
"Oh you must be a genius!"
