CONTAINER
Refers to an standardized shipping container, used for intermodal freight transport (intermodal means across different modes of transport, from ship or rail to road).
The most common sizes are either 6m (20 feet) or 12m (40 feet) in length, and 2.6m (8 feet 6 inches) or 2.9m (9 feet 6 inches) in height.
They can be hired for very cheap weekly rates, but have high transport costs. They're invaluable for creating dry storage at events, and are also used in the film and events industry as the support skeleton for huge sets / structures.

PIPE AND DRAPE (P&D)
A method for screening off an area, creating a booth, or creating wings for a stage. Uses vertical scaffolding in a boom base (known as a tank trap) or telescopic lighting stands to support a system of horizontal scaffold tubes ('pipe'). Black curtains ('drapes') are attached to the pipe either using ties that are part of the drape, or by threading the pipe through a sleeve / pocket in the drape, or by using other fixings such as zip ties / cable ties through eyelets in the drape.

PMSE
Abbreviation for Programme-Making and Special Events. Licence required in the UK to use radio mics, walkie talkes etc of certain types for TV/Film/Events production.

YELLOW CARD
IATSE Scheme that started in 1912 in the USA where a touring theatre or dance company would send their local labour requirements to the next venues on a tour, to ensure there were enough union crew available to staff the show. 
The scheme was originally based on yellow cards, but converted to an electronic system in 2013.
See also White Card.
