The Clinch is the embodiment of STI's. The Clinch can spread infection through proximity, saliva, blood, urine, and other means not yet identified by modern science. Some evidence suggests persons can contract a variety of infections from the clinch via text messages, msn, or even from excessive facebook creeping. Currently the only known prevention from contracting Clinch based virus' is abstaining from excessive contact with the Clinch.

Superficially uptight teacher, but really a dominatrix at night who specialises in anal insertion of a barometer.
