lyrics fucker
Any person that screws up the lyrics of a song.Frequently this is a result of the lyrics being misheard (also called mondegreens) or due to the original artist being hard to understand. Lyrics fuckers are normally exposed while singing along with the radio. There are a number of websites that feature "misheard song lyrics" and many of them are quite funny.
The old lady was rockin' with the Beach Boy's song about "My Little Poop Scoop". (Little Deuce Coupe).She's such a lyrics fucker.
