Posting a card for sale at such an egregiously high price (which doesn’t conform in any way shape or form to past sales), and causing everyone to gripe, “What is this guy thinking???!!”
See also: Trolesaler - a person who’s a member of this site for no other reason than to take advantage of the free access to the B/S/T and hawk their exorbitantly priced cards.
See also: Doing a Double-Brake (informal) - suddenly stopping when you see an eBay price that is so absolutely ridiculous that it makes you wonder if you’re missing something. Like, is the card a Venezuelan or something??
