Certainly an expression worthy of ‘Mean Twi’

She thought it was a dream come true when Twilight– The real Twilight– had asked a favor of her: She wanted her to throne-sit for a week or two so that she could visit the old princesses on their retirement vacation.
 
Of course, an opportunity to gain complete power over Equestria if only for a temporary time was something no power-hungry faux pony could ignore– so a little magic and the turning over of her regalia to her, and Not-twilight was in the seat of the government. She could order just about everypony around to her whims; How exciting!
 
Then came the petitions. The selfish requests for tax cuts by the nobility, the ridiculous demands for personal favors, and all the little families religiously pleading for blessings or that she kiss their snotty-nosed foals, as if that would magically make them embrace fr… fr… friendship later on once they were older.
 
No wonder Princess Twilight wanted to leave to visit the former rulers– how in the hay did she put up with this for months on end?! And yet, despite her pained suffering on the seat of highest power, Fake Twilight somehow managed to keep the country afloat with her wits, stern declarations and the… surprisingly reasonable dragon subordinate that the princess always had with her.
 
But the question had always popped up when Twilight’s subjects first looked at her gray-ish colors. And her answer was always the same: “I’m having a bad day. Now tell me what you want, or don’t waste our time.”
