Spanish isn’t widely spoken down here though. The origin is completely different. We have a habit of adding -o to various words in Australian parlance - bottleo for bottle shop, the name John becomes Johno, arvo for afternoon, ambo for ambulance driver and fuckos for fuckers. Your assumption it’s spanish is incorrect and culturally ignorant, and your attempt to dictate from that ignorance…tsk tsk tsk i’m afraid this is going to cost you.
