banksying

It's when you're going to break-up with someone and decide to plan an elaborate act far in advance. The breakup is calculated and perfectly timed out, rather than on a whim. For example, "That relationship was torture so I'm banksying him when we break up."

Historical perspective: Based on Banksy, an anonymous England-based street artist, vandal, political activist, and film director who in 2018 self-destructed one of his pieces of art immediately after a buyer purchased it at a Sotheby's auction.
