DEEP BURN ALERT ...
Stephanie McMahon let CM Punk have it Sunday night ... dissing the WWE star about the infamous ass-kicking he got in his UFC debut.
It happened in Chicago -- CM's hometown -- when the crowd started chanting Punk's name ... something that happens a lot when the WWE rolls into the Windy City.
Stephanie was ready for it this time ... and hit back with a shot cheaper than a fake Rolex ... but also hilarious.
