Formerly known as the "French Kiss", an open-mouthed kiss where much saliva is exchanged. Involves caressing the tongue gently with your own, and quite intimate. It is NOT good to cram your tongue into someone's mouth, however, as over-aggressively kissing, dribbling, and drooling is considered bad form.
"Like, oh my god. He just frenched me, and ew! He drooled all over me."
