The Patriots tight end was injured in the AFC Championship game, in which the Patriots defeated the Ravens, and was in fairly good spirits after the game. When he was interviewed by a reporter for ESPN Deportes in both Spanish and English, he happily played along, and delivered the one line that perfectly summed up exactly who he is. Asked if he would celebrate the victory, Gronkowski replied in Spanish.
"Si. Yo soy fiesta."
Translation: "Yes. I am party."
The phrase stuck with him, and he even wore a t-shirt with the phrase on it during the runup to the Super Bowl.
