A plain
girl, just another face in the crowd type. Nice, attractive enough; lacks
edge, attitude,uniqueness, style identity,
taste and sexual swagga.
I.E. "Yea, Nicole is still
single, but I
mean she's a Peggy and her boyfriend is still with her because its comfortable....shame".
Ex 2: "OH, I have
seen his NEW girlfriend, she IS SUCH a peggy..oh well for him."
