Simp is short for simpleton. Otherwise it's a term used to describe 'beta' type males who put woman on a pedestal for being hot or sending them really cringe messages for no reason. Typically seen more often on Twitter or Twitch where 'e-girls' are active and have a large following of horny guys or white knights (similar term tbh). Such as for streamers like Pokimane, Loserfruit, etc.

Get the simpmug. A new term gen z wants to use to exterminate wholesomeness in relationships. A man who gets flowers for a girl is now called a “simp” or if he kisses her on the forehead, even if they’re not “clingy”. Mostly used on TikTok, but it is mostly used as a negative term reflecting wholesomeness in relationships.
