People that use the terms "söy boy" or "cück" are highly insecure about their own masculinity.

Whenever I hear those terms I can't stop myself from imagining that person as a highly insecure person that tries to prove to themselves how masculine they are by making fun of people that remind themselves of their own self-perceived flaws.

Especially because the only people that are seemingly using those terms are incels, MGTOWs, red pillers and others who's whole world view is based on insecure delusions. And because I have never met a confident person in my life that would use such terms, but lots of complete losers that feel that it gives them some kind of power.
