the.com/revel

means To take loud, abandoned delight in something — dancing, feasting, or carrying on with unrestrained pleasure.

from From Old French 'reveler' (to riot, rebel, make merry), tracing back to Latin 'rebellare' — literally 'to rebel' or 'wage war again.' The link between partying and rebellion isn't poetic license: medieval revelry was loud, disorderly, and often literally defiant of curfews and authority, so the word for uprising slid naturally into the word for uproarious fun.
