Uncontrollable shakes caused by alcohol withdrawal. Getting drunk multiple times a day, every day, for many years is necessary to experience this. They start about 24 hours after your last drink, most notably in the hands and feet, and last for about 3 days unless you have a drink.
I ran out of money Bob, I haven't had a drink all day, I feel the shakes coming!
Uncontrollable torso shivers. Usually caused by some disturbing thought, visual, or sound. However, may occasionally be induced at random for what seems to be no reason whatsoever.
After smoking a lot of weed and you get a bad high, your body spasms or shakes uncontrollably. It will go away with time, just don't get as stoned next time.
Dude, we each just smoked a dub on our own. I have the shakes so bad. (Body uncontrollably spazzing.)
