When you arrive to the bar to meet people, and you are well behind them in terms of alcohol consumption. You order an Opener. An Opener is generally a triple shot of any hard liquor in a pint glass and topped up to the brim with a mixer of some kind. My personal fave is Triple Vodka + Club Lemon. This slang is common to the Mid-lands of Ireland.
