The valleys girls of San Francisco.

Teenage girls with no understanding of time or place. Good looking but completely air headed.

Will be highly offended when you trash her state with FACTS and LOGIC.

Get the bay girl mug.
Guys that think they're way too cool stereotype them. The stereotype is they're either a Bais Yaakov rebel and are obsessed with boys because they aren't exposed to them or are super yeshivish (pearls and black loafers). What they don't know is that Bais Yaakov girls are way more intelligent and in a conversation would be shocked at the stupidity they feel for being very wrong. Also, Bais Yaakov girls are not as obsessed with them as they'd like to think and they need to calm their egos. Also the more yeshivish ones commonly say things like "not the type" and refer to girls that talk to guys as sketchy.
more yeshivish bais yaakov girl: should we get pizza motzei shabbos?
other yeshivish bais yaakov girl: sooooo not the type, it's so sketchy!

random guy with huge ego: she's hot
other random guy with huge ego: dude, she's a Bais Yaakov Girl
