Floccinaucinihilipilification: The act of deciding that something is useless.
Modi has recently been begging Loki at every available turn for a "gill chij sammich." Loki has absolutely no idea what that is, and Modi eventually has had enough of his mama's ignorance and uncultured ways, and goes running to Gwen, who he's taken a huge liking to.
"Gwen!" he sobs into her denim-clad knee. "I wan a gill chij sammich, an Mama don know!"
Gwen sighs, pats his violet (Modi had also recently developed an obsession with every shade of purple available) hair, and tells him that she cannot make him one, the stove and oven are broken. This had been the result of several of Loki's failed attempts at baking a Betty Crocker cake mix.
"Toast?" Modi asks, looking up at Gwen with lavender eyes, and in that moment, Gwen has an idea.
Twenty minutes later, looking at the gooey innards of what used to be a toaster, Gwen has determined and concluded that one cannot use a toaster to make grilled cheese.
She hopes Tony can overlook the ruining of his state-of-the-art toaster.
