Something your friend, sibling, or cousin called you because you gave a spouse or crush.
Friend 1: Hey I actually have to cancel, I promised my girlfriend we would go out tonight
Friend 2: Aww man you’re a simp
Basically someone who really really really likes you for no apparent reason whatsoever unless they tell you that reason. Or someone who is always flirting with you, hangs out with you often, or always is around you all the time. Especially if they are dating or crushing on you if they've known for you a while.
A: Bro, there's this girl I like. Like...a lot and I don't even know why. I always like hanging out with her, and she flirts with me a lot, man.
B: Bro, you both are such a simp for each other.
A: Hey, can I have your number? Your super cool and amazing, I'd really like to hang out sometime.
B: Are you a simp or something? Get to know me first at least!
He needs to stop simping for her, just to prove her friends how much he’s a simp she spit in a shot glass and told him to down it. And he did. She did this a second time to further prove her point.
a person that is fr tweaking over somebody else, a simp is known for being obsessed with that one crush.
