If you’re the type who expresses themselves best with a keyboard-induced pictorial representation of a facial expression, and you like cups, check out Emoji Paper Cups. The cups will not only let everyone else in viewing distance know how you feel, but they can be altered as your mood changes.
For instance, in the morning, you can show how you feel before your coffee (whatever the emoticon for ‘stabby’ is), and then progress to ‘less stabby.’ Emoji Cups are also great for parties, for when you’d rather not mistakenly drink from your grumpy friend’s cup.
