Get some sex from a female. This isn't up for debate, the term has been around for a long time and it's in the dictionary.
No it's not "legs" plural, just leg. Leg is a euphemism just like "
get some ass" where leg and ass are
the stand in for vagina. To have sex. Women sometimes use the phrase to, because they think it's cute to use men's phrases.
"You´ll get some leg tonight for sure! Tell us
how you do! " ~
Van Halen, from "
Unchained"
