Peeka-no.

A verbal expression of annoyance over the patronising, imbecilic nature of parents who believe that holding their hands over their face immediately turns them invisible, and that removing their hands and then proceeding to say peekaboo, will amaze and shock the audience (often young children) into believing their parents are talented magicians who have an unbelievable power to disappear off the face of the Earth and then miraculously reappear.

*Baby looks in awe at spastic parent making goo-goo, ga-ga sounds*

Daddy: Aaaaaaaaaaa-Peeka-!

Baby: Peeka-no. Your face is behind your hands, I'm all over your damn trick Dad.
