I don't know any girls called Sharon or Tracy, however, I have extended my knowledge.
According to Google, TOWIE is 'The only way is Essex' and Sharon or/and Tracy comes up with 'Birds of a Feather'. It appears both are from Essex. Same cast? Sorry, couldn't be a***d to find out.
30 years ago, a past encounter with a customer's son who was 10 years old at the time and lived in Essex elicited the statement 'cor, you dun arf tawk fanny mite'. I recognised 'You', even if the rest was in a foreign language. There was a definite inability to compose a coherent sentence, just as I noticed on ITV's 'The Chase' the other day. The presenter asked the contestant 'If you was to win some money, what would you do with it?' My immediate thought was to buy him a copy of 'English for Dummies'.
Viz's Fat Slags I do recognise.
