break your legs

[Sin-Yu Tsai]

Can "break your legs" mean "good luck", or only "break a leg" does?

Thank you.

The "Break a leg" expression is appropriate in a limited context. It is based on the belief (in theater) that it "jinxes" somebody if you wish him good luck.

Break your legs does not work for me.

Having spent a lot of time in theater, I have heard the following a number of times.

A: Break a leg.
B: Thanks.
A: Even better, break both of them.
