It's playoff season and a Philadelphia team is in the hunt for a championship, which means social media will be more or less forced to consume Philly fans' uniquely zealous online fandom until their team wins it all or gets knocked out.

Currently, the Philadelphia Phillies are in the MLB playoffs and are preparing to face the Atlanta Braves in the National League Divisional Series tomorrow. In its excitement, the Braves' mascot Blooper, a sort of cream-colored Muppet thing, tweeted "One more day." In response, a Philly fan sent it a (likely unserious) death threat.

This was enough for Blooper to start "going in" on Philadelphia fans, insulting their toughness and the Phillies' mascot, the Phanatic, which is a sort of green space Muppet thing.

Philadelphia fans are notoriously protective of their culture, particularly their bizarrely monstrous mascots (see: Gritty), and they were all too ready to get into a flame war with what they perceived as Atlanta's lesser monster mascot.

Blooper has fallen victim to one of the classic blunders, which is Never Engage with Philadelphia Sports Fans Online Regarding Any Topic, and will now have to pray its team bails it out, lest it go down in history as the mascot that poked the proverbial bear. Now that would be a real blooper.
