For Vogue, Janelle Okwodu described Hayes's art as "impulsive, convoluted, and chaotic". Hayes based their stage name on their Instagram username, which they had put "no real thought" into until they started to perform music. They have described their music as "pretty genre-less". They frequently wear smiley or Juggalo-inspired clown face paint while performing. Raphael Helfand of The Fader described their music as "a combination of hellacious beats and cracked, unhinged vocals" and described their "sex-crazed-canine persona" as having "an extremely specific self-mythology". For the Chicago Reader, Micco Caporale described their music as "a perfect marriage between club-kid uncanniness and Juggalo attitude" that contained elements of breakcore, hip hop, and nu metal. Their music is largely techno punk and also has elements of heavy metal and electronic music. They have cited Missy Elliott as an influence on their music and image.
