Reverse 2 shield flex

Winning a game in Pokemon Go's GBL (Go Battle League) with the opponent having 2 shields remaining. You must also have used at least one of your shields.

Pokémon GO Addict: I love playing in the 1800 ELO range! Sometimes my opponents don't know what they're doing and end up reverse 2 shield flexing! It's happened 5 times today!
