a smartie party is where loads of boys and girls get together and the girls stuff smarites in there pussy and spin a bottle in the group of guys whoever the bottle lands on has to eat her out

When you eat dirt for the first time and leave your family to build a shack in the woods

A smartie-party refers to an ecstasy pill, due to the fact ecstasy pills are commonly round and small and come in different colours, quite similar to a 'smartie', the chocolate sweet. It ends with 'party' since it's a party drug.

'Smartie-party' was also used in 'LYTZ - 3 days awake' song, which was about alcohol and drugs.

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

Everybody gathers together and dresses in brightly coloured leotards, then has a party inside a unnaturally large smartie tube, located in the middle of a field.
