To mog someone means to be noticeably superior to them, whether in looks, build, style or performance.
Mog is a clipped form of AMOG, short for “alpha male of the group.” Dictionary.com says it can describe anything from physical appearance to performance on a sports team.
Today almost anything can mog anything: a new game mogs an old favorite, or a calm rider mogs a screaming one on a rollercoaster.
Not to be confused with $MOG, a crypto coin that shares the letters and has nothing to do with the slang.
