Because somebody at Soompi is a masochist or something, they compiled videos of every boy and girl idol group to debut in 2015 and came up with 99 fucking groups.
99 FUCKING GROUPS
It’s no wonder the failure rate is like 99%.
When you think about it, even the flop groups you know are not flop groups just by the fact that you know they are groups and think they are flops. Literally 90% of the groups that debut have literally nobody to even call them shitty untalented flops.
