Shaq Snowed Out of His Own Party

Shaquille O'Neal was supposed to host a party last night in Dallas for NBA All-Star Weekend -- that is, until the biggest blizzard in the city's history got in the way.

It was a Shagout!

Aura Nightclub in uptown Dallas -- say that before Shaq arrived at the club, the record-setting snowfall blew out some electrical transformers ... leaving everyone standing in the dark.

We're told O'Neal's people were already at the club when the lights went out -- and decided that between the heavy snowfall ... and the complete and utter darkness ... it'd be best if Shaq didn't roll in.

But the good news: The Cleveland Cavaliers' big man is set to host a party at Aura tonight as well ... pending the presence of electrical power.
