Boswollocks was confused for "boswellox" an actual word used for an anti-wrinkle treatment.
When Karl Pilkington mentioned it in a podcast, he and Ricky Gervais were talking about hearing it in an ad for shampoo. Stephen Merchant jokingly referred to it as boswollocks as in "a load of bollocks" because he didn't believe Karl and Ricky but they insisted it was a real word.
