カス in the context of 俺はやる lyrics by Wanyudo I can't figure out the meaning of the chorus from the song by Wanyudo. Particularly I have a problem with the word . The context is as follows (someone transcribed the full lyrics here, the link contains also a live performance of this song without the need for Spotify account): > > > > > ... > > > > From the first phrase () I guess is a noun and it might be used in the fifth meaning here: dregs (e.g. of society); scum; dross (and etymologically coming from ) for someone who lives only from "their mouth", i.e. this rapper. I imagine the first line () is something that he hears (from imperative form of ) and the meaning of what follows and the chorus would be an answer to it - something like " _this is how I live, this is the way of _." Is my interpretation correct?

(/) is a phrase used to mean "all talk", as in someone who talks big, but doesn't ever do anything they say they will.

So means "pieces of s**t who are all talk".
