It's an amazing feeling, full of tears and an overwelming sense of love that will drive you crazy and never let you go. This person will enter your life and never leave, even if it is just in your mind. You will lose sleep planning how you'll smile at them, or how what you'll talk about if you happen to bump into them. You'll plan your whole day around them, notice every change in them, every bit of happiness, every bit of sadness and you'll conjure up amazing fantasy's which you know will never come true but you tell yourself that there's always room for dreaming. You'll want to talk about them all the time, discretely of course, mentioning them as much as possible, practicing how their name will roll of your tounge, you might even try putting your surname on their name or the other way round. It may seem like i'm describing obsession, but it's really just love.
'when the person you love will never love you back.' 'oh, i haven't slept for weeks thinking if only they did love me back..oh well,i can dream.'

Vulgar idiom with American origin is typically used to imply that sexual activity with an African American or a black person is so enjoyable that one will exclusively seek out black partners in the future because of that.

Likely to harken back from taboos surrounding African Americans during the Antebellum period in United States history. During this period, large amounts of stereotypes existed around African Americans, many, also sexual. Racist ideas were held like that black men were considered to be animalistic and unable to control their sexual urges, which made having a romantic relationship with a black man, especially as a white woman, extremely taboo. All southern states had anti-miscegenation (anti-interracial marriage) laws, which weren’t abolished until June 12, 1967, by Federal law.

Many kinks surrounding black men specifically, like many kinks, are rooted in older taboos, which are now gone.

Once a woman sleeps with a black man, no white man will be able to satisfy her, so she sleeps only with black men from then on. Usually because of their girth and size, but also because they appreciate more types of women in general and have better moves.
