The act of celebrating an event before it has been fully resolved. Sometimes quickly followed by an embarrassing retraction when things turn out differently.
The Pulp Fiction quote by the Winston Wolf character "Let's not start sucking each other's dicks just yet, Gentleman." is a great example of premature joculation.

Get the premature joculation mug.
1.)When you celebrate a win by dousing the coach in gatorade before the game is over, and you end up losing.

2.)When you celebrate a touchdown and spike the ball before you make it to the endzone, and look like a retard when it is called back. (DaSean Jackson, T.J. Jones).
Dude, look at the premature joculation on the sideline, the game is not over.
