the.com/extravaganza

means A lavish, elaborate show or event, extreme in scale or flamboyance, often with more spectacle than restraint.

from Borrowed from Italian 'estravaganza' (extravagance, eccentricity), itself from 'stravagante,' meaning wandering outside the usual bounds — literally from Latin 'extra' (outside) plus 'vagari' (to wander or roam). The word first described flamboyant, over-the-top theatrical productions in the 19th century, and it has kept that sense of something that has wandered gleefully past the boundaries of good taste and modest budgets ever since.
