hug

HUG:
You can either use the "A" handshapes, like I do below, or you can grab onto the upper arms with "curved hands."
A single movement tends to be the verb form of "give a hug."
A double movement tends to be the noun form "a hug" or it can mean the process of "hugging."  You might see some people twist the torso a bit for emphasis, but I wouldn't unless I wanted to describe an extended (long) hug.

HUG:  Note: Deaf people hug more than Hearing people do.  It's a cultural thing.
