If you mean "record" as in "set a new record or new standard for performance"
then hold out your non-dominant flat hand, palm down, (lay it in front of you in
the air, pointing off to your dominant side. Then take your dominant hand and
form it into a fist and hold your dominant forearm in the air a couple inches
above the non-dominant hand and quickly, firmly bring the elbow down onto the
back of the palm-down non-dominant hand (think of planting a flag).

If you mean "record" as in "my grandma likes to listen to vinyl records," then
hold out your non-dominant flat hand, palm up. Make an "X-hand" with your
dominant hand. Use the "X-hand" like a "needle" (old fashioned record arm) and
circle it around the non-dominant hand as if representing the turning of a
record on a record player.
