Fake Accent University
Remember Ross from Friends who suddenly assumed an inexplicable British accent as a university professor? Remember further how Rachael made fun of him by placing a prank call from the fictitious Fake Accent University? Ha!
The fake accent seems to be an epidemic amongst South Asians in UK. No sooner do these guys hit the British shores and join biscuit packing factories or supermarkets in droves than they flaunt their superior air by junking their native accents at once and buying into the local one.
This is not a generalization and there certainly are exceptions.
