A Runaround Sue is a girl that seems to be loyal and loving to you, but is in realityplaying games with lots of guys to get attention and love. This term was first popularised by singer Dion in 1961.
When a female thinks it's "empowering" to sleep with a bunch of guys. Instead, being ran through like a track meet ruins perception of love and creates an unstable mentality in relationships.
A Female that gets around. A slut, tramp, whore, etc... Originating from the classic song "Run around Sue" by singer Dion in 1961, the songclearly explains a lose woman that "took my heart and ran around, with every man in down". It is a more classy way to call a girl a Slut.
