Twilight psychologically inverted her door. "Rainbow."
Rainbow Dash slowly chewed on her fries, paying no attention to Twilight as she continued reading her steamy Wonderbolt fanfiction.
"Rainbowwwwww," Twilight snaked up to Rainbow's side, peering over her shoulder.
Rainbow Dash imitated a cow in her slow and methodological chewing of her fries. Twilight ignored the noises that resulted and waved a hoof in front of Rainbow.
The pegasus brushed Twilight aside with a wing. She reached for another fry.
Twilight vacuumed up the entire greasy bag into her mouth. She then plucked the last fry from Rainbow's hoof and ate that too.
"Hey--" Rainbow finally looked away from her fanfiction just in time for Twilight to flee the room, cackling like a madmare.
