amorous kiss with tongue-play
French kisses are kisses in which tongues touch. These kisses are usually romantic. French kisses are usually reserved for those in love.
The Petit Robert 2014 French dictionary, released in 2013, added the French verb "se galocher" as slang for kissing with tongues. The informal English term "frenching" also means French kissing, as does the Quebec French term "frencher".
