A wowser is someone that hangs out at Your house, and makes everyone uncomfortable, know to help himself to the fridge, sure he may do the odd job to help out but usually ends in it costing you somehow.... Also uses the word wow way too much
The wowser is mowing the lawn... He didn't pick up any sticks and is ruining the lawn mower...........
