The true definition of smarty party is when a girl puts smarties up her pussy or asshole (if ur really that disgusting and wanna do that) and get them out, only using your tounge, before they melt, however many you don't and they melt means you have to go that many days without sex
Tina wanted to have a Smartie Party so she put 6 smarties in her pussy and Tommy only got 2 out before they rest melted, he must now go 4 days without sex. poor Tommy!

it is when a female or male unwraps a roll of smarties and sticks it up their butthole, and one by one pushes them out into their partners mouth. During this process, poo or fart may be released into the mouth.
