In French, the plural for kiss (kisses) is un baiser (bisous) but the plural can also be used in singular form as un bisou which functionally means the same thing, a kiss, but is a lot more casual/friendly/cute and I think English should have that too.
Like there's smooch which definitely sounds cuter but the act/word itself implies a more passionate gesture which is not at all the case with bisou.
Anyway just thoughts I'm having as I watch the worst French movie I'll probably see this year.
