On a VLive, Hongseok refered to ONF as "frogs in a pond". The phrase big frog in a small pond refers to a very important person in a place where there are less important people. This idiom alludes to a large frog that dominates other less challenging frogs. If you refer to a person as a big frog in a small pond it means that she/he is overqualified compared to others.
Also, small frog in a large pond. An unimportant or unqualified individual in a large organization or other setting. For example, Coming from a small school, Sandy felt lost at the state university—a little frog in a big pond. This phrase is the counterpart of big fish in a small pond.

1. [+792, -18] It's always the nugus who causes the controversies
2. [+758, -12] Pentagon needs to try an exorcism or something... any time they're about to do well, one of the members ends up causing a scandal
3. [+450, -13] Why does he have to say it like that?
4. [+61, -2] There's always a reason some stars never make it ㅋㅋㅋㅋㅋㅋ this isn't even his first controversy
5. [+60, -5] This guy has had so many scandals even before debut that even that rotten Yang Hyun Suk cut ties with him ㅋㅋㅋㅋㅋㅋㅋㅋ imagine being known as the kid thrown out by Yang Hyun Suk who is known to forgive pimping and drug distribution.
6. [+56, -1] This guy is always in one scandal after another ㅋㅋㅋ
7. [+50, -5] Hui had dating rumors right after E'Dawn left too, as well as several scandals by Hongsuk, so it's always funny to me to see their fans place all the blame on E'Dawn and act like the remaining members are the victims of his exit. I noticed this guy had trouble managing his facial expression when he was 2nd or 3rd on 'Road to Kingdom' and he would be glaring at his juniors when they were doing well on stage.
8. [+50, -2] He sure has a lot of controversies...
9. [+38, -1] Even a group at BTS' level would be called cocky if they said this about a rookie group so who does this nugu think he is? ㅋㅋㅋㅋㅋㅋㅋㅋㅋ
10. [+38, -0] Your group is lucky you have Hui dragging you by the collars right now
11. [+34, -2] The ONF kids are much better than Pentagon, who is he calling the frog in a pond?
12. [+28, -8] He acts like such an old fart on 'Road to Kingdom' when he's not even famous
13. [+26, -0] He's just been a ball of controversies since his YG trainee days...
