Oi! Oi! Oi!
Used by
Australians in most of the
circumstances where americans may chant U-S-A U-S-A.
This may be at one of the frequent moments of a fantastic sporting
performance by an Aussie, or when nothing's happening.
Believed to have been derived from the Welsh 'Oggie Oggie Oggie - Oi Oi Oi!', which might actually mean something...
Seems to have peaked during the 2000 sydney olympics.
Occasionally repeated several times consecutively, the 'Oi' chorus growing louder with each calling.
