Vodka martini

From Memory Alpha, the free Star Trek reference.

Vodka martini is an alcoholic Earth beverage prepared by substituting vodka for gin in a martini.

While at Vic Fontaine's Las Vegas lounge in the holosuite, Julian Bashir by ordered a vodka martini "stirred, not shaken". (DS9: "Badda-Bing, Badda-Bang")

This was an imitation of James Bond, who often says "shaken, not stirred".
