antibudgeting
The act of using money, which is earmarked for future uses, to purchase all sorts of unnecessary shit, essentially fucking up the family budget
My wife and I had 100K sitting in an account for our kids' educations, our retirement, and a vacation now and then, but my fucking bitch whore wife secretly got an ATM card that accessed that account, withdrew most of the dough when I was out of town, and used it to buy shoes, facials, painted fingernails, and a new iPhone, so I might have to divorce her on the grounds that she blew our savings to shit by engaging in antibudgeting.
