Referencing a twitter joke, a "Tungsten Arm" O'Doyle (or just "Tungsten" for short) is when the Los Angeles Angels of Anaheim manage to lose a game despite historically dominant performances from star players Shohei Ohtani and Mike Trout.
Fan 1: "Did you hear Ohtani got 2 home runs and 10 strike outs last night? And Trout hit a cycle!"
Fan 2: "Yeah, but the Halos still manaed another "Tungsten Arm" O'Doyle..."
