Horrible music that the general population likes. Ass Rock is typically 70's and 80's rock music that mysteriously became popular despite how bad the song actually is.
Example 1
Guy 1: The song "pour some sugar on me" by def leppard is the best song EVER!

Guy 2: No it's not, they lyrics don't make sense, it's such an ass rock song.

Example 2:
