its a thing to help roll ur rim up on ur coffee cup. your from Mexico so uv probally never heard of such a thing.

For a few months every year at this coffee shop we call Tim Hortons (Named from a Hockey Great, that played for the leafs) theres prizes under certain cup rims. theres like 20 cars to be won. 100+ Ipods to be won, Money prizes to be won and Millions of coffee and donuts to be won. and some dumass invented this thing to roll your rim up. but really its just dum cause its not hard to roll the rim up at all. must be for retards or something HAHHAA
