An adverting jingle that gets stuck in your head. An unwanted piece of music that it is harder to shake than a dingleberry stuck to your short hairs. A tune wedgie or earwig with commercial purposes.
What's that you are humming?
Oh man. I was watching football all weekend and now I got a Chevy Truck jingleberry. "It is OUR country...." Just shoot me.
After hours in the cold, slushyblizzard, I had jingleberries clinging to the ends of my hair and beard, so I ate one jingleberry at a time in order to rehydrate.
