<P> In English informal speech, a French kiss, also known as a deep kiss, is an amorous kiss in which the participants' tongues extend to touch each other's lips or tongue . A "kiss with the tongue" stimulates the partner's lips, tongue and mouth, which are sensitive to the touch and induce physiological sexual arousal . The oral zone is one of the principal erogenous zones of the body . The implication is of a slow, passionate kiss which is considered intimate, romantic, erotic or sexual . Actually, the sensation when two tongues touch, also known as "tongue touching", has been proven to stimulate endorphin release and reduce acute stress levels . </P> <P> A French kiss is so called because at the beginning of the 20th century, in the English - speaking world, the French had acquired a reputation for more adventurous and passionate sex practices . In France, it is referred to as un baiser amoureux ("a lover's kiss") or un baiser avec la langue ("a kiss with the tongue"), even if in past times it was also known as baiser Florentin ("Florentine kiss"). The Petit Robert 2014 French dictionary, released on May 30, 2013, added the French verb "se galocher"--slang for kissing with tongues--making it the first time a single word described the practice (except in Quebec, where the verb "frencher" means French kissing; Australia, where the term "pash" is used; the English verb" shift" is used in casual conversation in Ireland; the German verb knutschen; the Italian verbs limonare and pomiciare; and the Hungarian verb megcsókol / csókolózik). </P>
