Doesn't look like it to me, but we don't know what words were said. It's usually called when refs hear specific derogatory remarks, I think.
Like, remember when Diggs taunted the Pats CB on his way to a TD last year? He was clearly looking back at him and holding the ball out as he went into the ez. I was really word that would get called, but it didn't.
I think if you action the ball towards a player or get really insulting with your words, then they throw it every time.
