If you've ever been to an ODEON cinema, the likelihood that you've sat in your screening and pondered what the individual letters mean is slim - but people are just realising what the name actually means, and their minds are blown.
Of course, Odeon traditionally is the name for ancient Greek and Roman buildings built for musical activities such as singing, musical shows, and poetry competitions - it translates to 'singing place'.
But social media users have been discovering that there's another meaning behind the popular cinema chain - and it's probably never even crossed your mind before this point.
