A margarita is a cocktail consisting of tequila, triple sec, and lime or lemon juice, often served with salt or sugar on the rim of the glass.

Although it has become acceptable to serve a margarita in a wide variety of glass types, ranging from cocktail and wine glasses to pint glasses and even large schooners, the drink is traditionally served in the eponymous margarita glass, a stepped-diameter variant of a cocktail glass or champagne coupe.

Device for museum heists and object of desire for mischievous, adventure seeking boys.

"When a character has to get through glass, they cut out a perfect, round hole while leaving the rest of the panel untouched. It's a stealthier, quiet alternative to smashing the glass. 

It's a suction cup with an attached lever, with a cutting element on the end of the lever. The suction cup is applied to the glass, then the lever is moved around in a circular motion, cutting a circular area out of the glass. A Phantom Thief or spy might use this method during a heist." ( tvtropes.org )
