A person who never talks while you are out doing things with them and your friends
"Dan is such a clam he never will talk"
A "clam" is a highly unsociable creature that lacks out-going ambitions. If you have a clam in your social circle they more than likely are always the person to deny doing anything besides staying at the their house and hanging out in their basement and smoking bongs. A typical clam will deny being a clam and will typically call others by their own putrid title, inorder flaunt their insecurity of their well-deserved title onto others.
