"A Ruben" in Australia is a slang word for having a day off work "sick day", when you're not really sick

The word "Ruben" was named after NRL Legend Ruben Wiki, a legendary rugby league player from the 90's to 2000's"
His surname "Wiki" rhymed with the word 'Sickie", which is Australian slang for sick day or day off
