We're not too sure about this so-called etiquette expert...

William Hanson told Cosmopolitan UK that he can tell what class you're in by the words you use... but honestly, we're taking his comments with a pinch of salt because being 'middle class' can mean a hundred different things. We also all know that we pick up loads of phrases from pop culture and colloquialisms from where we live, so we're not 100 percent sure that Mr. Hanson knows what he's talking about with the words and phrases he has chosen. So, ready or not, if you use these words, William will class you 'middle class':

• Pardon?
• Toilet
• Pleased to meet you
• Bubbly or ‘Fizz’
• Kids
• Avo
• Movie
• Uni
• Booze
• "I’m done"
• Catchment area
• Fitbit
• Vegan

Vegan? Movie? TOILET?! What is this man on about... It comes after Tatler and Vogue both lined about attributes that they believe make a person posh. There was the one about what you do on Christmas day that angered a lot of people last year, and also one about what items in Ikea make you upper class... Cool.
