Least Favorite Puppy

The counter part to favorite puppy, least favorite puppy is an adjective that means the opposite

Something unfavorable or uncomfortable.

ie. not favorite puppy.

A slang term to describe something, someone, or an action you like/dislike. Originally from the 20th episode of the Chuckle Sandwich podcast starring Jschlatt, Slimecicle, and Ted Nivison. As a kid, Ted called his beanie baby "favorite puppy" instead of giving it an actual name. It then became a joke among them to use it to describe things, and confuse future guests.
