A Sandy bit is an award that you receive in the following situation
 
  • You are playing golf at Rowlands Castle Golf Club
  • It’s the men’s Wednesday evening roll up 
  • Your ball has entered a greenside bunker "in regulation"
  • You get down in two strokes
  • Therefore you have a gross par… Which is known as a Sandy Par
So you win a BIT (25p)
Of course it’s also possible to play better than par and get a Sandy Birdie
