If you ever find yourself playing Rob Gronkowski in flip cup, make sure to go easy on him because things could get ugly if he loses -- and if you're playing giant flip cup, things could get real ugly. 

Gronk was a guest on ESPN's SportsNation this week and during his time on the show, he teamed up with host Michelle Beadle for a game of flip cup. 

Beadle and Gronk were good, but not good enough and the pair ended up losing a close one. Gronk then proceeded to do what I normally do after all of my flip cup losses: he smashed everything in sight.

The best part about Gronk's reaction is that we can now add "giant red cup" to the list of things he's spiked this offseason.

Since the Patriots won the Super Bowl on Feb. 1, Gronk has spiked a bouquet of roses, a watermelon, a Lionel Richie record, a Lombardi Trophy cake, an electric guitar, a pumpkin and a mustache-shaped piñata. The piñata even had candy in it.
