Somebody who works in a fast-food outlet flipping hamburgers, possibly lacking the ability to do anything much more mentally taxing. Also loosely applied to other unqualified, unmotivated workers who come into contact with customers. Anybody who is forced to talk to the public while wearing a baseball cap bearing the company logo (and who is not a baseball player) probably qualifies.
I wanted a cup of hot coffee, but the burger flipper behind the counter said they only sell cold coffee now, in case people sue.
Someone who orally pleasures several females and/or males within the course of 12 hours.
The guys and I all have to say that that girl was one hell of a burger flipper.
