After all, how will people know just how fabulous your birthday party was if there isn't a handy hash tag that populates their feeds with all the super-awesome snaps from the night of you having an awesome time, drinking awesome shooters, listening to awesome music and not to forget, soaking each others awesomeness.

Kate even pulled out the crimpers from the box in the loft for the occasion.
