Complicated drinks

Something we learned at the Halloween-party. You take a small paper-bag filled with a powder tasting something like raspberry, lemon or mint. You pour the contents into your mouth, mix it with your saliva while going "mmm-mmm-mmm" preferrably loud. Then you take a shot of vodka, clink your glass with everybody elses, pour it into your mouth, shake your head vigorously as to mix the drink, and then actually swallow. An extremely complicated way of drinking a mixed drink. And I can recommend not doing it twice!
