clams up 

When an idea or a plan is exceptional.

We should head directly to the pub for beers; CLAMS UP! (while holding thumb pressed against fingers pointed toward the sky)

Clam Up 

To suddenly keep unusually quiet, often in regards to the divulging of information.

Carol clammed up about the incident at the bakery, so we never did find out whatever happened to Nate.

class up the joint 

To add a touch of refinement or elegance to an otherwise seedy or unsavory location, grouping, or endeavor.

The crystal doorknobs in the dive bar really 'class up the joint'.

Clam Up 

When a girl who seems interested suddenly decides that she will not have sex.

"Hey girl, I thought we were going to get down. Why you gotta clam up on me?!"

Dude, this chick was all over me and then she totally clammed up!

clam up 

Like tea bagging, but when a girl does it, ie a passed out young man has a photo taken with a woman's naked vulva on his face.

OMG, he got so wasted last night and Vickie said that she was going to clam up, and she totally clammed him up. Check out the photo on Flickr!

Up Class

Exhibiting coolness and style; where pretty, rich, and hip people like to be.

"I was at the Kettle and Stone Brewery in Boulder, CO last night, and that place is so up class!"

"Clubbin' with Kim and Kourtney last night, those bitches are totally up class."
