Rudy Fernandez had just flopped ridiculously and caused a common late game intentional foul to be called a flagrant. Batum, clearly frustrated with the game and with the flopping, decided to get his money's worth and show the Spaniards what a real flagrant is. I can respect that.
GIF request for Batum mouthing "I'll **** you up" towards the Spanish bench. Spanish flopping was pretty disgusting to watch, but granted, a groin punch was probably not the best way to respond. I hope Spain gets smashed by Russia while crying the whole way.
They should probably toss him out of the Olympics. He could have at least pretended it was an accident.
