Contraction formed from the words 'he is the man'. Originally derived from a mural (graffiti)which which was painted in a wall in suburban Brisbane (Australia)which depicted the face of a young Jesus like character and the words 'he de man'.

It has been argued that the words underneath the painting do not refer to Jesus but to the name of the actual artist.

Currently the word hedeman (or hedemann) it is used not in a Christian reference manner but to indicate that a particular person is exceptionally good in a particular field, sport, etc.
