Simp

A guy who feels intense emotions and acts mushy for a girl he’s probably only known for 3 months just because she she gave him some or he’s hoping to get some. But these days it’s a loosely used word and can reference anyone who even values or respects women.

X: I heard him on the phone with Jenny telling her she deserves the world.
Y: Bro he literally met her last week... He a Simp.

OR
Guy: I respect women and don’t objectify them.
Incel: SIMP!!!!!!
