An act where one person puts at least one finger into another person's anus and shouts loudly "YABBA DABBA DO!!" at the same time. This is a prank and is meant to be done in surprise however it is known to be sexually stimulating to some people. A self yabba dabba is when you insert your own finger into your anus suddenly, usually by accident when looking for your wallet.
