One of the most shocking losses of Week 12 came in Jacksonville, where the Ravens blew a two-score lead in the final six minutes of a 28-27 loss to the Jaguars. 

Following the game, an NFL fan took to Twitter and called for the Ravens to let Lamar Jackson leave at the end of the season, and the quarterback did not take kindly to that. 

After watching Jackson complete just 50% of his passes against the Jaguars, the fan wrote that the Ravens should "Let Lamar walk and spend that money on a well rounded team."

The Ravens quarterback was tagged in the tweet and we know he definitely read it because not only did he respond, but he responded with something that could put him in hot water. Jackson told the fan to "STFU," while also including a vulgar NSFW insult that we can't show here.
