'Wantics' is the kind of word that only an extremely bored and under-challenged worker could come up with while passing through a quiet period of work, or 'down time'. It's meaning is basically the mindless banter that comes from the quiet times in work when not much else it to be immediately achieved - 'Work Antics'. A temporarily lazy and un-motivated action at work that can be explained as nothing other than a 'Work Antic'
