bug in the buns

Bug in the buns is an expression used to say there is a problem. When there is a bug in the plastic bag of hamburger or hotdog buns, it is never pleasant. This phrase can be used to say there is an issue or it can be used to say something is out of place.

Me: Uh oh, we have a bug in the buns.

Jen: What’s wrong?
Me: The microphone for the talent show isn’t working!
