A specific hand movement in which you stick you hands out directly to your sides (or a bit higher) with your palm flat and facing the same way you are. This is a movement that Zac Efron uses several times when performing "Just Wanna Be With You" in the third installment of High School Musical.
Thst girl does the Zac Efron hand movement so well, I think I might just marry her.

Get the Zac Efron hand movement mug.
The action of waving at someone as you walk over the road if they stop for you. Is often performed at (zebra crossings) in Britain. Despite it being law to stop there for someone it is mandatory that we say thank you for obiding the law.
Friend #1 I saw Sheila doing the (British hand movement) again as she crossed the road again.

Friend #2 Oh yeah she’s from England.
Friend #1 K then.
