Get the Crocodile Smilesmug. A little smile you make when you're embarrassed, usually by awkward situations or when you do something "stupid".

Get the Salamanca Smilemug. A trendy pose where the participants can hardly be bothered with a full smile. A smile created more with ones eyes than mouth with lips closed and the corners of ones mouth just ever so slightly turnt up.
