A man who puts a woman before their friends, even though the woman doesn't give a shit about him.
This word is also used by butthurt 10 year olds whenever they see a couple together and see a man being respectful towards a woman, even if the woman respects him back. That definition of the word is wrong.
If you're gonna use a word, use it right.
Jeremy's putting himself down to please Anna. What a simp.
