Dumb and Dumber, AKA, Seunghoon and Mino - the rapper line. The nickname was born in WINNER TV episode 2.

When given a day off in Japan, Seunghoon and Mino both want to go to different places. 

But to be partners, what does Mino /lie/ say to attract Seunghoon?

And is Seunghoon dense enough to agree?

Apparently, he is. 

And while there...

In episode 4 during the trivia portion, the nickname arose again.
