A humorous and perfectly cromulent portmanteau of "sarcastic" and "fantastical." That which is sartastical is fantastically sarcastic, or indicative of extravagantly fanciful sarcasm.
Person A: "Problematical is a perfectly cromulent word."
Person B: "It embiggens even the poorest writers among us."
Person C: "That's ironical, isn't it?"
Person D: "Actually, that's sartastical."
