Going out of your way to impress a girl/make her fall for you. Too simp youd have to buy her flowers or something to impress her.
Guy 1-"Dude I just brought Rachel some flowers and she loved them"
Guy 2-"Bro stop being a simp"
You’re such a Ryan for wanting to date that girl even though you have no chance. Simp
A simp is a guy who obsesses and chases women they are attracted to even when she has expressed disinterest in him.
If she leaves you on “read” for months but you still message her and like all of her pictures.. you’re a simp.
