Many variations on this sign. (Lots of different ways to kiss I reckon.)
Don't worry overmuch if someone doesn't kiss the way you do. Er...I mean, doesn't do the sign "KISS" the way you do.
In the main version of this sign you form each hand into flattened "O" handshapes and then you bring the fingertips together in front of you while puckering up your lips (as if kissing someone).
KISS:
0:00 / 0:00
Note: This version of KISS looks a lot like the sign for MORE. Except MORE is done a bit lower and doesn't pucker up.
This next version is also used by some people.
KISS (version):
0:00 / 0:00The graphic is a bit off. Instead the thumb is wrapped in a bit more and the tip or pad of the thumb is pressed to the fingers. This version is almost the same as the sign for HOME except that the KISS handshape is much more flattened (but not totally flat -- it is more like an extremely squished "O" hand.) Also for the sign HOME you don't pucker up. But you do pucker up for all versions of KISS.
