—Girls

From The Extended Group

A —girl is a moniker given as reference to a particular girl someone in the group encountered, is interested in, or is individually acquainted with. An arbitrary quality of the person (or circumstance of the encounter) usually becomes the first syllable of the pseudonym, with "girl" following as the suffix. Hence, a girl sitting in front of you in your biochemistry class might become "biochemgirl."

Motivation for using this cryptic designation may range from a desire to keep the person's identity secret to a lack of knowledge of the said female's actual name. Often this is done simply for the sake of having a collective reference point for discussing girls who are only rarely encountered. In this way, the —girl identifier is an example of one of the many Seinfeld parallels in group behavior.
