Brexic victory (n, usually singular):

1. A victory which is both damaging in the short-term, and yet also leads to staggering long-term losses.

2. A disaster both tactically and strategically.

3. A victory which no one should have wished for had they known the present or future consequences.

4. (pejorative) Any of the above senses, with the implication that the 'victor' is deluded as to the nature of their 'victory'.

Portmanteau of Brexit and Pyrrhic victory.
The Embargo Act of 1807, as a response to the Chesapeake–Leopard Affair, both failed to damage British exports - they found new markets in South America - and damaged both the US economy and public confidence in the fairness of the US government. It was a short-term diplomatic failure, and a long-term economic disaster for the USA; the bill's passing is an early example of a Brexic victory.
