Halloween's gonna be extra lit in Boston on Wednesday ... 'cause the Red Sox are having their World Series victory parade ... and we'll be streaming the whole thing!!
If the locker room celebration was any indication of what's to come ... expect absolute chaos -- cannonballs, champagne and beers flying everywhere, and probably some drunk speeches.
Of course, Rick Porcello stripped buck nekkid right after the BoSox won on Sunday night, but we're assuming he's gonna keep things PG this time around.
There's an extra bonus with the parade falling on All Hallows Eve .
