Sandbagger is one of the most commonly used words in Polinguistics. It has a wide variety of meanings, but is probably best described as an individual whose behaviour is either dubious, unorthodox, annoying, or any combination of the above. Behaviour of this type is known as sandbaggery, and to engage in this type of behaviour is to sandbag. Aiden Dunne was the first to use this word, but it has spread to other Poliners, and despite the seemingly endless number of meanings for this word, everyone seems to understand its intent no matter how it is used.
Tav once had a job filling up bags of sand.
