Drunk people tend to start acting strangely as soon as the hooch takes a hold of them, and their behavior only gets worse as they get drunker and therefore feel less inclined to care how they're acting.
This is especially true if the drunks are drinking as a couple, because their special relationship fuels the flames of passion in their hearts, causing them to make a scene as a drunken duet.
This season you're sure to encounter some of the drunken couples on this comical list by Andrew Bridgman and Paul Westover at various holiday functions, so bear this terrifying truth in mind- they all started out as Fun Drunks!
