Profligate- wasteful of money or resources
Ex: It is easy to become profligate these days with the myriad of streaming services to sign up for. I just checked my recurring payments tab on my credit card website and it looks like I may have purchased a $30-a-month subscription to Public Access Estonia: Private Edition. Well, looks like I have two options: I can either cancel, or become New England’s biggest kiiking (a form of extreme swinging in which you pass over the top bar to complete a full loop) devotee. And guess who just, in real profligate fashion, booked a flight to Tallinn, Estonia for the world kiiking games. Kiik on, my friends!
Wastrel- someone who wastes things or opportunities presented to them
Ex: The Wastrel Jackson family blew their paychecks on gambling and blow each week. Every Saturday afternoon you could find them buzzing around the slot machines at Mohegan Sun like moths drawn to a bright light. Their faces were caked with so much powder that you just assumed they ravaged a dozen jelly-filled Krispy Kreme donuts, but if you put your ear up real close to their chests you could hear their hearts firing off like rotary engines. Uncle Steve’s heart exploded last week when he hit triple 7’s on Diamond Miner Deluxe, and he received a full traditional burial next to Attawenhood of the Mohegan Tribe.
Quiescent- dormant, temporarily inactive
Ex: The Ripstik lay quiescent in the garage. Many moons had passed since that curvaceous beauty had touched gravel. The Ripstik had seen the rise and fall of the hoverboard, and with it, the passing of time, the changing of seasons, the unerring ebbs and flows of the universe. One day the Ripstik would rise again, and the tides of contention that washed upon society would cease, and the second age of the Ripstik would arrive like the chariot of Messiah from the heavens above (excerpt from Ripstik 2: This Stik Still Rips, Baby).
I distinctly remember "wastrel" being used in a video game (Grandia 2, a billion years ago) and "quiescent" in the last chapter of Moby-Dick. Can't recall any specific instances of "profligate."
