In Australia you can do higher education at Tafe or University. Some fields of study you go to both (not very often though). So we named our mate a Tuni. T=Tafe, uni=University. Example: Phil: So you're telling me you do uni and tafe together? Bazza: Sure am. Phil: Did you realise that makes you a tuni?
