Aftershock is a liqueur drink produced in Canada by Jim Beam Brands and distributed by Munson Shaw Co. of Deerfield, Illinois. It has a thick, syrupy consistency and is available in five varieties:

Red (Hot & Cool Cinnamon)
Blue (Deep Cool Minty)
Black (Blackcurrant)
Silver (Apple & Caffeine)
Green (Thermal Bite Aniseed)
Aftershock was first marketed in 1999, and marketed primarily to younger drinkers. All varieties of Aftershock contain 40% alcohol by volume (80 proof). Poplular in the UK, the drink spawned several drinking games, the most common of which being "The Aftershock Challenge", in which participants have to hold a shot of red Aftershock in their mouths without swallowing for as long as possible. Another challenge associated with Aftershock takes advantage of the powerful fumes that evaporate from the drink. A drinker is to down a shot, hold the hand over the top of the shotglass (as to keep the fumes sealed) and then to inhale them up the nose; the intended effect is a powerful alcohol-induced headrush.
