ARMY Monkey Brain 

A term made up by friendless K-Pop fans to insult ARMYs, but they ended up making a fool out of themselves by ever thinking this was funny when, in reality, it is extremely corny.

ARMY #1: A K-Pop fan said I have an "ARMY Monkey Brain" because I rightfully called out some K-Pop groups for chart manipulation and racism.
ARMY #2: Wow, well, that name is cringey. Did they really think that was comedic in any way?
ARMY #1: They did, and that's why I can never take them seriously.
