How would it make one a "simp" if they buy pussy? They don't have to idolize, or have feelings for, or defend the women (things that would label someone a simp). Also, it's not really true, your first statement. It's certainly not totally true. Not even close. For a couple reasons.
"SIMP" is a hilarious, ridiculous, and silly word too btw. Just sayin. Heh.
