One who sits online attempting to shame/insult random men into rushing out and asking out every woman. Simp-pushers tend to troll men's channels and female dating coach channels, using slurs like "you must be gay". This is a primitive (albeit ineffective) attempt to make the man feel as if it is compulsory to date.
The fact that simp-pushers are so concerned over whether men they will never meet go on dates or not is actually very creepy.
Simp-pusher: "Why aren't you asking out every woman you see and taking her on expensive dates? Are you gay?"
Random guy: "Um..do I know you? Why does it matter to you what I do? Creepy".
