Actually... if a person got REALLY REALLY BORED... and started digging into it... back in the day Bonnie Tyler was singing "... living in the Powder keg and giving off sparks" but by the time the music editors got finished with it... the sound of "powder Keg" came out Polygag and everyone just sang it and had no idea what it was...
Some thought it meant "Crowded city" others thoight Political arguments... in reality Polygag is not even a word and it was just a mumbled part of the lyrics in "Total Eclipse of the Heart"
