means A contest so lopsided it stops being a competition and becomes a formality — also used for a wild, no-expense-spared party or, literally, a tire failing catastrophically.

from Rooted simply in 'blow' + 'out' — something bursting outward under pressure, first used for an exploding tire or gusher. The sense of a lavish, uncontained party arrived by the same logic: emotions or spending blown wide open. Sports commentary borrowed the image in the 20th century for games where one side's lead explodes past any hope of a comeback — the contest, like the tire, has ruptured.
