It is when a male is overly submissive to a female and gains nothing from it. So overly submissive that other guys cringe and feel ashamed when seeing them. This applies to males in relationships when they are so submissive that they say literally anything to be in favor with the female.

Get the simpmug. Simp stands for simple minded/simpleton. Someone who's so simple minded and dumb they're easily played by societies bs and falls into all the racial/dividing/categorical ass thinking/shallow/trendy non sense. Can never think for themselves/hive minded/echo chambers, etc etc.
Stay simpin defining ppl by inaccurate colors, dividing and being of such a simple minded character you generalize everything like a simp/simpleton would.
