The nicest possible way to refer to ones penis dork, wang or johnson. so called because only a mummy or a daddy can see this bone.
this is 10 times better word when you are old enough to say dick without ur mum telling you off. Becuase all youre mates think you're strange.
OOOWWWWWW right in the mummy daddy bone!!!!!!!!!
