Cock and Roll 

A musical style that is a poor offshoot of rock and roll. Cock and roll bands are characterized by homosexual undertones, angsty/whiny/shallow lyrics and generally shitty and unoriginal instrument "playing." Cock and roll music is particularly popular in today's music scene, considering the prevalence of bands that fall squarely into that musical category. (ie, Fallout Boy, My Chemical Romance, All American Rejects, Green Day, etc.)

The Jonas Brothers are a popular cock and roll band.
