The act of wearing two condoms to ensure no accidents occur.

Often when the female is rather promiscuous

Just like wearing a belt and braces to ensure you're trousers don't fall down.
Woman: "Why are you putting two condoms on"

Man: "Belt and Braces my love."

Get the Belt and Braces mug.
Two-fold protection, overly cautious (used in UK). Belts and suspenders (the US).
Babies, that's why I always wear a condom, two if the girl's ugly... belts and braces.
