Lay-back
Someone who walks too slow while talking with their fellow lay-backs. They block the entire sidewalk or hallway, leaving you no choice but to plow through them and tell them to piss off under your breath. They often show up at the worst time, like when you're trying to catch the bus.
A word used predominately in Australia and New Zealand to describe when a person lies on their back and another person ejects goon (cheap cask wine) into their mouth for a particular period of time.
This can be done from a great height or, for example, hanging in a tree, in which case it is known as a "trick pour".
