i think its an australian term, used to live there so it stuck, we use to watch the rodeos there, kids (not mind tho!!) wud ride the poddy bulls in ring, last about 2 seconds. i use to hate thought of rodeos until i realised even the champion guys only lasted about 8 seconds on the bulls. dont ride the horse rodeos though, but then i dont like horses at auction either, brings lump to throat.
