Jan Brady 

When a turtle neck is worn alone. With nothing over it. The way Jan Brady wore hers. If it is under a sweater or sweatshirt. Its is just a "Jan".

Oh no.. I have a hicky!! I guess I'll wear a Jan Brady today.

jan brady walk

When someone (usually a girl) walks while bobbing their head side-to-side making their hair move funny. See Jan Brady and in particular, the Brady Bunch movie.

Guy 1: Who's that chick? Why's she walking so funny?
Guy 2: Yeah, she's got that Jan Brady walk going on. Weird.

Jan Brady Effect

When, in a situation such as a double date or casual hangout involving two girls, it can clearly be noticed that one girl is prettier/smarter/funnier/more superior than the other, much like how Marsha was always better than Jan in The Brady Bunch. Therefore, the poor girl who is inferior to the other seems to experience the Jan Brady Effect.

Troy: "Wow, Gavin. You sure do have a 10 right there!."
Gavin: "Yeah, she's quite beautiful. I'm very lucky. I just feel kind of bad for your girl. Candance seems to just be all around better than her."
Troy: "Yeah. We clearly have the Jan Brady Effect going on here."

The New Jan Brady 

When someone emerges into a newer, better, funkier, sexier, bolder, more confident and stylish version of themselves after an intentional transformative experience.

Holy hell! Who IS that??? They walk with such confidence, their hair swinging with the sexy funk of a grade A mod. It's The New Jan Brady!
