A term for the very enthusiastic support of the British tennis player Tim Henman. Henmania is seen mostly at Wimbledon, and is a phenonemon that grips the nation every June and July. Despite the fact that Tim Henman has never actually got past the semi finals, the bandwagon seems to roll on every year. However with his ever increasing age, and the emergence of Andy Murray, Henmania is rapidly declining, if not actually finished.
Henmania is gripping Britain, as Tim Henman makes the semi finals of Wimbledon.
