In american football all the players wear shoulder pads which
them effective v-shaped bodies so that they look like cartoon
In rock music, a lot of the players play guitar or bass so that
effective shape of their bodies looks as if they are holding and
their own erect genitalia.
All that is left to do is to combine these two visual tropes so
either football players with their exaggerate shoulders do more
manipulating of their own exaggerated sexual organs, or rock
musicians, which I was thinking would be easier, do more
of exaggerated shoulder pads while they are already
their own exaggerated sexual organs.
So this is an idea of a band where the only visual trope is to
emphasize the width of the shoulders of the band members and
emphasize the phalicness of the guitars and basses.
