A hand sign for friends.
Place your thumb against the palm of your hand, then cross your middle and ring
finger. The pinky finger represents the word 'you', the index finger represents the
words 'and I', and the crossed middle / ring fingers represent the
words 'are tight'.
Now, with your other hand, point to your pinky, index, and crossed middle / ring fingers, respectively. "You and I are tight".
