Psy, who has recently brought many laughs with his sweaty behind, has explained the reason behind why that happened.

Psy updated his me2day on August 25th writing, "I saw my picture as I came back to Korea...?,? that happened because I had an ice pack on my hip while sitting because it was hot... as if something like that can happen to a butt.�?,?." He also added, "What if this will lead to [the nickname] 'butt sweat'?"

On the post, he uploaded the screen captures of when he was dancing to SISTAR's "Alone" on 'Super Star K4'.

When he turned around while dancing, everyone on set and all the viewers got a good look at the huge wet spot that formed on his butt and after the airing of 'Super Star K4' the term 'Psy's butt sweat' was trending on various internet portal sites.

Most people assumed that the water on his behind was sweat because he is already known for his sweaty armpits.

Fans left comments after reading Psy's explanation saying, "I thought you had�hyperhidrosis," "So it was melted ice," and "Totally funny."
