The word breaks down: 'Misstel' an Anglo-Saxon word for dung (boo-boo) that comes out of a Mistel bird. Toe is the word for twig.

"What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing? But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils. Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils" (1Corinthians 10:19-21).
