Lying about the facts to make yourself feel better about being a weasel and dodging your responsibilities.
The word originates from the infamous hockey player Chris Pronger, who spreads the untrue rumours about irate Edmonton fans burning his furniture, including his baby's crib, after he asked to be traded from the Oilers. Although Pronger could not be reached for comment, it is assumed he was trying to divert attention from the fact that he asked to be traded from the Oilers after completing a measly one year of his five year contract.
I totally prongered about being sick today. I told my boss I had massive diarrhea, but in fact I just hate my job and didn't feel like going.
A Pronger or "throwing in a Pronger" (prhong-her) is the act pinching a large portion of chewing tobacco (usually Skoal Mint) and juicing it in your bottom cheddar. Pronger's tend to be quite large and cause an abnormal shape in the bottom lip and are named in after the noble Chris Pronger.
