Invented by RH from Hartlepool. When you get a suntan or are sunburnt whilst wearing an unsuitable piece of clothing, or sitting with part of your body in the shade. Leaving you with visible white bits. This has no relation to the taxi driver tan.
Look at her shan-tan, she looks like she's got 'Best of Both' tits!
