baisoter

A rare, old-fashioned diminutive of baiser in its original chaste sense, meaning to kiss lightly and repeatedly, in a playful or tender way — essentially confined to older literature today.

• Le poète baisotait la main de sa bien-aimée. — The poet kept lightly kissing his beloved's hand.
• Les enfants baisotaient leur grand-mère sur les joues. — The children kept planting little kisses on their grandmother's cheeks.
• Ce mot a une saveur désuète, presque comique aujourd'hui. — This word has an old-fashioned, almost comic flavor today.

Because baiser itself has shifted to a vulgar meaning in modern French, baisoter now reads as strange or unintentionally comic to a modern ear — use embrasser or the phrase faire des bisous instead.
