The way that
who are obviously in love hold hands. It involves slightly tracing each other's palms and gently scratching
the other persons palm, looks
a bit like your fingers
are doing a sort of jelly fish motion. This is usually accompanied by looking into each others eyes and a stupid smile. Most of the time this handshake is done with
your hands in the air as apposed to the side (like in traditional hand holding).
It should be noted that
if the two people
doing the handshake are not in love it looks
Person 1: So, how are things going
with you and that
Person 2: Not well. I saw him doing the I Love You Handshake with another girl.
Person 1: Oh, I'm sorry. They must be in love.
