Isn’t this the definition of a simp?

He is selectively nice to some in hopes of getting sex or some favour and never nice to other women whom he’s not physically attracted to

Simp (/sɪmp/ ⓘ) is an internet slang term describing someone who shows excessive sympathy and attention toward another person, typically to someone who does not reciprocate the same feelings, in pursuit of affection or a sexual relationship.[1][2] This behavior, known as simping,[3] is carried out toward a variety of targets, including celebrities,[1] politicians,[4][5] e-girls, and e-boys.[6] The term had sporadic usage until gaining traction on social media in 2019.[7
