Digibutter.nerr

digibutter.nerr is a nerdy website that Francis from Super Paper Mario visits often. It is apparently a forum filled with geeks and nerds of all sorts who seem to love butterflies. Francis declares that he shall take 'HI-TECHNICAAAAL' pictures of Tippi, whom he calls Francine, and post them all over the forum. After he creates Tiptron, Francis mentions how Tiptron earned him the "Elite Nerr" status on digibutter.nerr's forums.

Trivia

 * The name comes from digital butterflies, which many of the forum members seem to enjoy. Its .nerr top-level domain seems to be derived from Francis's quirk of constantly saying "nerr", an impediment he may share with other members of digibutter.nerr.
 * When selling Tiptron to Mario and friends, Francis incorrectly capitalizes the "d" in "digibutter.nerr".
 * Shortly after release of the game, a real digibutter.nerr forum was created, where mostly discussion of Super Paper Mario is made.
