Budweiser Brazil have devised a new way of remembering the people you met on a night out for when you get so drunk you can’t remember what happened.
They have called it the Buddy Cup and it contains a chip which the person holding the cup pairs to their Facebook account. When the person clinks their cup against another cup, they become friends on Facebook.
I actually quite like the idea, I think it takes the awkwardness away from asking someone for their number or even asking if they wanted to hang out again.
Only problem is, you might need to keep a firm hold on your cup all night incase it gets mixed up!
