Get the Monkey Brain mug.When you take the monkey brain you form by stretching your skin tightly around your ball sack tightening the skin till it resembles a minature brain and placing it out the top of your waist line so that it resides on your belt buckle
To create a Monkey Brain Belt Buckle. Place your brain to belt buckle position and then call upon a near by friend to bear witness to it.

Get the Overthink Monkey brain mug.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.

Get the ARMY Monkey Brain mug.A stupid and annoying person that probably deserves to be shot or worse. This type of person constantly acts like an idiot but still thinks they're smart even though they literally have rocks for brains. And they are so annoying that they act like a real monkey
