Podkabluchnik

(подкаблучник)Russian slang phrase for the word SIMP.

I guess it can be directly translated as "the man who is under the (female)high-heel". (под каблуком)
Also has a group of emojis associated with it: 👠👠👠

Originated from the Russian YouTube streamer known as Glad Valakas

Those men who pay women on Onlyfans are Podkabluchniki.

My friend is such a Podkabluchnik, he spent a lot of time, money, and gas on trying to impress a girl who is not even interested in him.
