American Sign Language: "finish"
(over, done, already, did...)
FINISH:
The sign for "finish"
is made by placing both of your open hands in front of you.
Each hand should face you, with your fingers pointing upward.
Twist both hands quickly a couple times ending with the palms pointing
(somewhat) forward. You can also do this sign with just a single twist
which makes it seem more "final."
Now let me show you a version of finish that means "Knock it off!"
Here is a version that means, "Aw, go on, you're teasing me!"
"I'm not falling for that--you silly!"
Note: The eyes aren't really "closed" on this one...just squinted due
to a big smile.
