A highly contagious condition that seemingly settles itself upon slack-arse waitress' causing them severe pain when the hoovering is mentioned or when more than three drinks need taking out.

One who can do balloon- modelling with the inside of one's throat. A massive asset at childrens parties and in the bedroom. Usually Kingstanding females possess this talent, but it has been known for more men to be born with this amazing gene.
