"Master of Bitchcraft: Advanced Level"

"Forget your wands and potions; true power lies in the perfectly timed eye-roll and an insincere smile. This 'Bitchcraft' shirt is for the highly skilled sorceresses among us who have mastered the dark art of Pissing People Off and Smiling Sweetly. It's not a hobby; it's a lifestyle. Wear it and watch your enemies spontaneously combust from suppressed rage. Warning: May cause confused admiration and an inexplicable urge to apologize for nothing."
