Much like that of Thirsty Thursday, it is a day to enjoy spirits and other intoxicating substances to prepare for the coming Friday generally with a group of friends you would spend Friday with. It may also include a sort of fight in the backyard or during the party hence the other meaning of "Throwdown." Lastly, everyone must throwdown some money for the booze, it's a BYOB without the hassle.
Hey man, you got money for Throwdown Thursday tonight?
