A bond so strong between friends that it goes all the way back to your childhood, hence sandbox. Can be between any group of friends, and genders.

A proposal of marriage made by two young children for fun (ex. when playing house), or for real. Neither is expected to uphold their end of the bargain, and it is often forgotten as the children age

A delightful sexual act in which a male urinates into a womans vagina before or after sexual intercourse. Preferrably afterwards... but then again.... This act is usually done out of spite or in rare cases for fun.
