PML mfs

Obnoxious individuals from one of the larger Skylanders themed discord servers, most infamously, PML (Portal master's lounge). These users tend to have an ego a few sizes to large and often flip between thinking their opinion is "objectively correct" and telling those who disagree that "there are no objectively bad skylanders". Some PML mfs think they're better than other skylanders fans because they make (often low quality and unoriginal) YouTube videos.

Portal master 1: "I got called a dumbass for thinking Drobot was really good on PML today"

Portal master 2: "Those PML mfs really need to learn some manners!"
