He's probably referring at the technique they've used to get the groupon.com domain from a guy living up in UK. This guy bought groupon.com with the intention of building a group coupon business. While he was sitting on it, the real groupon guys built the real thing and registered the trademark in US (which, somehow, extends to the UK) and told the poor english guy to either take 250k for the domain or prepare to be sued. He accepted the money and everyone was happy.
