PSY is no stranger to making over-the-top performances...and the viral king just might have outdone himself in his latest concert.

For a Christmas concert in Korea, the "Daddy" singer included one of his famous covers that usually imitates a well-known female act (in the past he's done Beyonce and Lady Gaga). This year, he went for K-pop girl group EXID who broke out domestically late last year with their super-viral hit "Up & Down." PSY re-recorded their catchy song and even donned an exploding bra to really really show us something we haven't seen from the star.

It'll leave you feeling a little uncomfortable, a little confused, but ultimately entertained which is exactly why PSY is the star he is today.

Watch the performance above and give EXID's excellent, original version of "Up & Down" a spin. There's a reason the clip has over 37 million views right now:
