4. Joe Diffie, "Leroy the Redneck Reindeer"
Bad things happen when Rudolph calls in sick. His understudy is a pickup-driving, overalls-sporting, "down home party animal," who follows Christmas carols with the rebel yell. It gets worse; in the most cringe-worthy of this 1995 song's lyrics, Leroy the Redneck Reindeer prompts Santa to drape his toy bag with the Confederate flag. Beyond any holiday lists, this is one for the country music hall of shame.
