open (one's) legs(redirected from open their legs)
open (one's) legs
vulgar To have or be receptive to having sex with someone. Most often said of a woman. My mother told me not to be opening my legs or I wouldn't find a husband, but I think she's terribly old-fashioned. As long as they use protection, it shouldn't matter how often anyone opens their legs.
