Yo, Nice Skirt

A term used by south korean rapper Park Chanyeol in the song, "Forever", from EXO's album, Ko Ko Bop. It's said to indicate that he is complimenting a girl on her skirt but truly, he is looking at her behind.

Girl: *walks past boy*
Boy: *eyes dat ass*
Girl: *catches him looking*
Boy: Yo, Nice skirt. *nice save*
