Answer: ACCENT
Step-by-step explanation:
I remember this from band when I use to go a couple years back in middle school. It is an accent, mainly used in music, but also can be used in everyday life, ya heard. Even Eminem uses a lot of accents when he raps, if you listen to Godzilla by Eminem and Juice WRLD, you can hear at times when he uses accent in his rapping (volume wise, not language.)
