It’s just up the road, and I missed it.

The What the Fluff Festival, a celebration of Marshmallow Fluff in its birthplace of Somerville, Massachusetts, brings new meaning to WTF. On Saturday, Fluff enthusiasts piled into the town’s Union Square to listen to Fluff-themed poetry slams, sample Fluff-bearing foods, and play games like “Fluff, Knife, Bread” (a modified version of Rock, Paper, Scissors).

The tradition all started four years ago when the gooey white stuff was receiving some negative press. A bill was proposed to limit the number of times a week school cafeterias could serve the “unhealthy” Fluffernutters, a regional sandwich favorite combining the joys of Fluff with peanut butter. In response, Mimi Graney created an event to promote Fluff advocacy. This year’s showing was especially passionate since the Fluffernutter may soon become the state’s official sandwich.
