when two people are laying down together, typically a
couple with one of them on their backs, the other has one of their legs reached over the other's body. Such a
case would be a man laying down, with one of his girl's legs going across his body while the other is parellel with his own... such a position typically brings the
couple's faces together and is ideal for cuddling, kissing, and generally intimate.
Sam, I love your overleg... it's so
smooth today!
Your overleg going across my
belly gives me a feeling of comfort and intimacy. Plus, you finally shaved!... so your overleg isn't giving my belly road
rash!
