For years now I have heard kids use the word "versus" as though it is the present tense of the imaginary verb "to verse", meaning to oppose, to play against, to match up with, to combat.
As we set off to Saturday morning soccer I am asked "Who are we versing?" When I tell Marcus that Richmond had a big win he asks "Who did they verse?" I have probably used it myself when responding to the under-11s, just to save time and explanations to a probably unreceptive crowd.
This new word has now made its debut in the newspapers. At the least The Age Online has adopted it.
