CLUELESS 699
Welcome to Clueless, our informal weekly clue setting competition. The idea is to compose a cryptic clue to a given word or phrase. The winner of the previous week's competition both sets the word to be clued and judges the entries for the current week. The judge's decision is final and reasons may or may not be given at the judge's discretion. It is customary for the judge to donate a virtual prize to the winner.
Multiple entries may be submitted and new competitors are particularly welcome. Please give an explanation if you think it might help. Clues should be submitted by 6pm (UK time) on Wednesday September 4th.
Today's challenge is:
GROIN VAULT (5,5)
Good luck!
