I wanted to read 'how to get a bikini body ready in a month' and as I clicked on the link the top of the page is advertising Ben & Jerry's ice cream  Sad

Same here, & to add also got a McDonalds advert before the video started. Just what you need to see...

Any modern age girl can get a bikini body in a month. In their own minds they already have one. From what I see, the fat chav cows buy a humungus tacky and tasteless "designer" (LMFAO) bikini and actually believe it looks good whilst straining to contain 23 stone of kebab curry, and vodka shots which only get worked off looking thru catalogues,going to the post office to cash the benefits cheque, swearing at their kids, Jawdon & Britny, from the sofa at the top of their voices instead of getting off their fat arses, or spelling every word wrong on Chavbook! Can't wait for this summer's outstanding beach hippos dressed up like over inflated, mascara wearing pigs. It is so funny!
