The Caulin Davis Effect

The product of including someone in your band, only to realize shortly that your band now sucks horribly. Symptoms include excessively being made fun of, the odd desire to add two-stepping to all your performances, frequently getting the stinkeye from others, or just sucking all together.

Woah man, why is it every band that this guy is in sucks?

That, my friend, is The Caulin Davis Effect at work.
