Clique (Klik) n. A small group of people who do not readily allow others to join them.
The strangest thing happened last night. I was snubbed. Royally. And this is why I found it strange - I was snubbed by people, until last night, I regarded as friends. Anyway, the immediate upset, followed by the later anger has now just given way to indifference. I guess I just need to be more careful about who I give my friendship to in future.
