An unorthodox method of discharging the contents of a condiment bottle. This approach starts with a period of furiously thrusting the bottle up and down and then quickly slamming it on a table. This results in some of the condiment spewing out of the bottle, and hopefully onto the target. This technique is considered obscene by most standards, and is sometimes hard to control.
The desperate man had to lauer the bottle to get some ketchup onto his hamburger.
