Least Attractive Denominator (Lad)

The least attractive denominator (lad) is a phenomenon that occurs on dating profiles, where the least attractive person pictured in each group photo is the owner of the dating profile.

Jerry: Every one of this girl’s profile pics is in a group photo, most of the girls are attractive but I can’t tell which one is her.
Chad: It’s always the least attractive denominator (lad), in this case the fat girl wearing too much eye makeup. Sorry man.
