Jimmy Kimmel launched the 4th edition of "Mean Tweets" on Wednesday. after the CMA awards.
This grouping of witty responses featured big names in country music like Dierks Bentley, Old Dominion, Kacey Musgraves, and Rascal Flatts.
There are some seriously mean (and funny) insults in this batch and a lot of people with a really good sense of humor about themselves. There's even the obligatory Nickelback jab.
