Are you telling me you've been drinking, or I should be? 'Cause I'm about to uncork a bottle of wine here pretty quick.Drink.
SC Top 10 #1

After reading everyone else's responses, they seem to understand what this is about, and I'm getting it now. Here's my answer to what I think you're asking:
Kenny caught a brilliant TD, races into the end zone and does the "SHH!" gesture to the crowd. That can either be interpreted as "Don't cheer so much, this is just me being awesome," it could be "Silence the critics," which is the most common usage.
Kenny got the penalty for that or his '303' symbol he puts up to represent the 303 - his area code back in Colorado.
Either way, that was a BS penalty to call on him for that play.
