This is a group of people who learn the dances for kpop songs and perform them in front of a street audience somewhere.
Some examples of groups are:
Howl (not on youtube, resides on Instagram)
KingDoms (if you know what i mean (; )
Red Crew
MAXXAM
Or an actual kpop group where you perform on stage but you do not actually have to make up songs because that is hard but you just go through the life as a kpop star and what you do and also making jokes on stage and so on and so forth.
If it is like kpop then there will be a big group consisting of at least four girls and at least four guys and there will be units inside of them a girls unit and guys unit.
Like nct but less people.
