What is this white pimple like thing in my throat?

There's this white pimple like thing in the back of my mouth near that thing that hangs down. I got it Saturday, but by today (Wednesday) it doubled in size. It doesn't really hurt, just annoying since I can feel it constantly whenever I move my tongue. What is it? And how do I get rid of it?

It's not strep throat, I've had that before and it's definately not that since there's just one white pimple and not several. And no, I haven't put anything in my mouth that was dirty or infected.

It's called tonsillolith (tonsillo=tonsils and lith=stones). They are small food particles that gets trapped in the folds of your tonsils. They stink. When they get big, its starts coming out. The only way you can remove it is to express it using your fingers or a long q-tip. Or if you can inhibit your gag reflex, use a water pik and channel the output to that particular fold. Make sure waterpik is set to the lowest setting because it can hurt you. I know this because I have this once in a while and I have my doctor look at it. He was surprised that I know what it's called. I have doctor friends too. Or to eliminate gettting it anymore, have your tonsils removed. I didn't consider the latter.
