Cover art for Cowboy Bob lyrics by Butthole Surfers

I think it's about some sort of pain that will not go away, like a sense of betrayal. He got burned last night an woke up with it. Instead of moving on, he puts it back in, choosing to linger on the pain he's experienced, not realizing that he is the reason for his pain and wishing it would go away.

@WhiskeytimeCowboy I like this interpretation, that's actually useful advice!
