Coined in a Hampshire College Mod kitchen many times over, a Hampshire Martini is any mixed drink made using a needlessly large Mason Jar in lieu of a traditional Cocktail Shaker. Despite the mention of martini in the title, any cocktail recipe can be employed, as long as one assembles the contents in a jar over ice, shakes or stirs accordingly, and then uses the Mason Jar's lid to strain the liquid into the appropriate glass: another mason jar.
"Any real Hampshire student, given the do-it-yourself nature of such a wonderfully liberal college, would not be caught dead without making their cosmopolitans up Hampshire martini style."
"Even the neo-marxists?"
"Sweetheart, especially the neo-marxists."
