Anne Weying, while temporarily bonded with the Venom symbiote, kissed Eddie Brock in the movie Venom. She did this to transfer the symbiote back to him.
In detail, Anne attacked Roland Treece and bit his head off to save Eddie. After that, she greeted Eddie, grabbed him, and kissed him while the Venom symbiote moved from her body back into Eddie. This was necessary for Eddie to regain the powers of Venom and fight Riot.
