look up any word, like swag:
The monster that hides in stores and convinces you to buy random stuff that you don't need or are not on your list. This creature especially likes to hide in stores such as Walmart and Ross.
Chelsea: OMG! I went to Walmart with a grocery list and totally got attacked by the Splurge Demon on my way to the checkout!

Patrick: Really?! How much did you spend?

Chelsea: I splurged on $50 worth of random crap :/
