Johnny Manziel has ensured himself a hostile reception if he plays against the Seattle Seahawks next season.
The Texas A&M quarterback is set to be drafted in May, and he has already set about ruffling a few feathers in the big league.
As Seattle fans celebrated winning the NFC Championship game against the San Francisco 49ers last night, booking themselves a date in New Jersey for Super Bowl XLVIII in the process, Manziel could not resist creating some controversy.
The Seahawks fans have been crucial in their teams push for the Super Bowl, with the sound emanating from CenturyLink Fields actually registering on the Earthquake scale in the past, and have in recent times become known as the '12th man'.
But Manziel is keen to ensure people do not forget where the "12th man" idea originated...
His old school Texas A&M.
Posting a picture to his instagram account in the aftermath of the Seahawks - 49ers game, Manziel attached this comment:
"REAL 12th Man".
There is already some hostility between the NFL franchise and the college team over the whole "12th man" issue.
The Aggies actually sued Seattle when the Seahawks began to use the phrase, and in 2006 the NFL team agreed to pay the university a licensing fee.
In fairness to the Texas school, their 12th man tradition dates back to the 1920's whereas the Seahawks only retired the number 12 jersey in 1984 as a tribute to the fans.
Expect another earthquake when Manziel visits CenturyLink Field.
