It's the Rage Guy face on top of Chemistry Cat. He typically says "FFFFUUUU-" to express rage. The chemical symbol for Fluorine is F, and the chemical symbol for Uranium is U. Therefore, "Fluorine Fluorine Fluorine Fluorine Uranium Uranium Uranium Uranium" becomes "FFFFUUUU-"

Oh my gosh, that's actually pretty clever! :)
