Use a standard tumbler, pour a shot or two of vodka in it, then quite a lot of Orangina (you MUST use Orangina; none of that cheap Minute Maid orange soda crap in the Cordless Drill), a tidge of Squirt citrus soda (the basement where I drink this engages in fierce brand loyalty) and a slurp of sour mix. Stir nostalgically, and serve.
