What does NAGGIN stand for? 

Naggin

A naggin in Ireland is a 200ml bottle of spirits. Major brands of vodka, whiskey, rum, and less often gin, are commonly sold in this size in off licences, especially independent (non-chain) shops, typically at 37.5% to 40% ABV. Naggins are more common than half-bottles (350ml - known as a "shoulder"), though for the less popular majority of products neither size is available, only the 700 mL EU standard bottle size . The naggin bottle is typically the shape of a large hip flask, suitable for placing in a pocket. According to the Oxford English Dictionary, naggin is a variant of noggin, a word of uncertain origin recorded from the seventeenth century and meaning a small quantity of alcohol, usually one gill (0.25 imperial pints (140 mL)). Tomás S. Ó Máille derives it from the Irish naigín, cnaigín, a small wooden pail with a capacity of two glasses.Naggins, particularly of cheap vodka, are very popular among youths, under-age drinkers and students. They are often implicated in binge drinking.
