Put your arm down, dumbfuck!

Dan Uggla, after his 9th-inning grand slam to put the Marlins past Philadelphia. 

You're excited, I know.  But raising your arm while rounding the bases following a home run, any home run, possibly excluding one that just brought you back from three down in the 9th to win the series, is super douchy.  

Three things you should never do whilst playing sports:

1) Pump your fists a la Tiger Woods, Derek Jeter, Rafael Nadal.  Super douchy.

2) Kick your opponent in the balls.  Super douchy.

3) Raise your arm in celebration as you round the bases following a home run.
