Simp is English. Learn your own fucking language before you go around criticizing mine.
The hillbilly side of you just showed itself.
Simp orginally meant a man who pays for OnlyFans or some other service, like Twitch streamers - because he's lonely and is looking for some kind of connection.
It's a slang that has developed to mean usually white knighting for women, feminist men or even just submitting to a woman.
Simping means paying a woman and having delusions about how she likes you, when you're just getting used. Maybe over Twitch, OnlyFans or then just in real life.
Simp is a word which is not used in good manner - It's intention is to attack.
