Mezz

The phrase meant to define an internet shitposter who frequently spreads misinformation regarding random topics in an awful attempt of humor, and uses a back & white photo as a profile picture on almost & every social media platform.

Person 1: Remember that Mezz guy from our class?
Person 2: You mean the guy who constantly paraded frog propaganda and internet shitposts?
Person 3: Yeah, that guy.
