(Male def.): Someone who is usually very nice and very kind, but he sacrifices time with the boys to be with girls. A simp may be seen laughing at girl's jokes all the time, constantly agreeing with what they say, etc. This may not be a bad thing; simp's are usually very kind and the best people. However they can be annoying whenever they ditch the bros for hoes (girls but 'hoes' rhymes so its better).
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.
