The act of kissing someone; an exchange of kisses.
From ex- 'out' + Latin osculari 'to kiss,' from osculum 'mouth, kiss.' The prefix ex- intensifies the action of kissing, and -tion makes it a noun.
This delightfully obscure word meaning 'kissing' shows how Latin lovers and poets had elaborate vocabulary for affection—we've mostly abandoned 'exosculation' for simple 'kiss,' losing ornate romantic language along the way!
