Help Identifying a Trick

Hey everyone! I'm dropping by to ask for your help. I'm pretty new to this, and I'm looking for a specific trick to learn more about, practice, and eventually add to my repertoire. Thanks in advance to anyone who can lend a hand! I'm also happy to help out where I can, even though my knowledge is pretty limited at the moment.

P.S.: Sorry about the image quality.
