Chalk this up as a rookie mistake.
Or being dumb.
Or having no class.
Or all of the above.
Former University of Washington Husky football standout and Carolina Panthers rookie linebacker Shaq Thompson took to social media following the Panthers win over the Seattle Seahawks with a profanity laced video posted to SnapChat which basically said, in short, "F--k the Seahawks."

Veteran teammate Mike Tolbert tweeted the video with the caption "Shaq you are a rookie you can't do this lmaooo 😂"

As it turns out, coaches, teammates and fans from the same city that cheered for you during college don't take too kindly to that as evidenced by Thompson's Twitter feed.
