Is there a linguistics term for an expression that derives from the sound of another word?

The example I have is pejorative, so please forgive me. I will try to text it in white, so if you want to avoid it--don't highlight the lines below (and if this doesn't work--I'm punting with HTML5--I apologize!):

Catholic > Cat licker

I'm curious if there's a name for this type of derivation, and also if it typically happens for negative connotations mostly or if positive expressions develop this way sometimes as well?

Thanks so much!
