When the beat fire but ... starts rapping

A phrase used when the song has a good beat but the rapper (...) on it ruins it.

Originally used on the internet with different phrases, it became popular in a different format in late 2023.
Starting off as an untrue statement about young Richmond, Virginia-based artist, Nettspend, the term quickly blew up on Twitter and started being used for other artists.

The first seen use of this new saying was from X user @kanjlrou on November 21, 2023.

Bob: That new Ice Spice song is ass. The beat was good though.
Bobby: When the beat fire but ... starts rapping
