when you kiss someone you know you're not supposed to, because you know your feelings for this person are borderline and you haven't thought about the situation properly, that's a gray kiss
M: I kissed him even though I wasn't supposed to and we are kinda friends and bla bla bla...
K: so, you gave him a gray kiss...
