From Wikipedia, the free encyclopedia.
In The Netherlands, 'going double Dutch' means using two types of contraceptive at the same time: the man wears a condom, the woman swallows an oral contraceptive. This is supposed to be the safest type of sex, and is recommended by a lot of official institutions, because it simultaneously protects against pregnancy and veneral diseases (like AIDS).
In English slang, talking double-dutch or Double Dutch means talking apparent nonsense or in in a confusing and contradictory way. The term may be used to describe a speech or policy statement so inconsistent or difficult to follow that a hearer/reader might say "it's all double-dutch to me". Holland used to a rival to England and the Dutch phrases were a form of a contempt.
It also means playing jump rope with two ropes and two people jumping simultaneously. There are at least two other people turning the ropes.
