A wandering beyond proper limits; an excursion or sally from the usual way, course, or limit.
The state of being extravagant, wild, or prodigal beyond bounds of propriety or duty; want of moderation; excess; especially, undue expenditure of money; vaid and superfluous expense; prodigality; as, extravagance of anger, love, expression, imagination, demands.
My parents survived the Great Depression and brought me up to live within my means, save some for tomorrow, share and don't be greedy, work hard for the necessities in life knowing that money does not make you better or more important than anyone else. So, extravagance has been bred out of my DNA. David Suzuki
It seems as if an age of genius must be succeeded by an age of endeavour; riot and extravagance by cleanliness and hard work. Virginia Woolf
