Probably completely unrelated, but this reminds me of the 1 line chant we used in hide and seek:

when the 'seeker' had finished counting they would bellow "Illey alley ole-up" to warn the 'hiders' that the hunt was on.

If hiders could sneak back to touch home and shout "Billy 123" before the seeker spotted them and beat them to it they were considered 'not out'.

It was a very close run thing sometimes, and a lot of adreniline involved in the decision whether stay hidden and risk being out, or make a run for it!
