Drop Trou

One absolutely great thing I love about the Net is that you can find out how to spell just about anything.

Was just wondering about the origin of "drop trou" which I figured was "drop trousers" but thought might be spelled "drop trow" since that seems a more correct phonetic spelling.

I was wrong. Here it is.

And an important piece on Charlize Theron's proclivity for reciprocal trou dropping.
