Basically you have a word like let's say.. strawberry.
You make another word for it like uhh, Irrorooketatai.
and the next person has to use it in a sentence. such as.
Irrorooketetai tastes like awesomeness XD.
and then that person uses another word.
me: Red= futarioni
user: futarioni is a color.
user: next is plaid: lolokini
other user: lolokoni etc etc
other user: lolipop: shiiro
