look up any word, like donkey punch:

A neighborhood in Scituate, Massachusetts, soon to be a terminus for a reinstated (dormant since the 1950's) commuter railroad.
The Greenbush Line will travel from Boston's South Station, making stops in Quincy, Braintree, Weymouth, Hingham, Cohasset, and Scituate.

The upper-South Shore is the last area in Greater Boston without adequate commuter transit. There is a Commuter Boat from Hingham, but most parking is reserved for Hingham residents, at discounted rates!

A boorish, vocal group of Hingham residents tried every trick in the book to "de-rail" the Greenbush Line. A Boston Globe columnist from nearby Weymouth mercilessly, and justifiably, described these NIMBY activists as petulant primadonnas.
