Hitty-Titty

Hitty-titty in-doors,
Hitty-titty out;
You touch Hitty-titty,
And Hitty-titty will bite you.

These lines are said by children when one of them has hid herself. They then run away, and the one who is bitten (caught) becomes Hitty-titty, and hides in her turn. A variation of the above lines occurs in MS. Harl. 1962, as a riddle, the solution of which is a nettle.
