The same as footsie... it consists on playing with someone else's feet with yours, its a way of flirting or cuddling.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

the less cool way to refer to playing "footsie"
