The act of eating a whole can of pringles within a half hour while crunching obnoxiously into the phone or trying to talk to friends, and in the act of this communication, more pringles exit your mouth then entered said orfice.
Believed to be derived from ancient Scots, it originally implied that a Pringles was unfit for human consumption.
However in the modern tongue, mingers pringers may be used to answer a question on the suitability of an object. Mingers pringers may also be used in whatever way the user requires, and should always answer that it is Aberdonian slang if questioned.
Proper pronunciation is agreed as something similar to mungers pring-ers.
