After a woman's husband/wife, common-law spouse, or boyfriend/girlfriend passes away, the woman's kiss becomes a 'Widow's Kiss.'

She has a unique awareness that any time she kisses, it could be the last time she ever kisses again. Therefore each kiss is held with fierce passion and lust like it's the last one she will ever have.
"He was kissed by a woman with a 'widow's kiss' and he couldn't let go , because he hasn't felt this kind of lust for life in any woman he's kissed before."

"To say farewell with a widow's kiss."
