perenseja
A generic placeholder name used for a woman whose name is unknown, forgotten, or not worth mentioning. It is similar to saying what's-her-name or so-and-so (it is the feminine form of perencejo, typically used as the fourth name in a specific sequence of Spanish placeholders: Fulana, Mengana, Zutana, and Perenseja).
Look, there goes perenseja.
