Denzel Curry is an artist from *Miami, here he uses the word on himself. Obviously he’s not Asian.
““Gook” is Miami slang for being a misfit or strange. Instead of taking the term in a derogatory way, Denzel embraces his weirdness.” -RapGenius.com
Seems to back up Davis understanding of the word pretty well
EDIT: this stupid board won’t let me post links, just look up the song at rapgenius.com and click the lyrics
