fuck song 

A folk song that includes obscene lyrics, two examples being "The Necrophiliac Song" ("My name is Jack, deedle ack, deedle ack, I'm a necrophiliac...") or "Barnacle Bill the Sailor"; a bawdy song.

It's fun to sing fuck songs.

what-da-fuck song 

A song that has a very strange meaning, and makes you ponder.

*the song "what's my name again" by blink 182 starts playing, a key example of a what-da-fuck song*
Jim: what the fuck?
