A person who is a "simp" is a boy who falls in-love with a girl. Not just that. They will also try to win the girl by acting very nice to her and not other people.
Simp: "Hey. Do you want my lunch?
Girl: "Okay."
Simp: "Take my Money!"
Girl: "Thanks!"
Simp's Mind: I think I'm winning her.
Girl: "Okay."
Simp: "Take my Money!"
Girl: "Thanks!"
Simp's Mind: I think I'm winning her.

Get the Simpmug. (noun) A pathetic beta male that gives money to thots, and who's most likely subscribed to their subreddit or Twitter feed where he defends her honor in order to get validated by his peers and hopefully get some pussy crumbs.
