More of a sniglett, but is very commonly known as the black streak build-up of wet road debris (mostly dirt & who knows what else) that collects on the back of your shirt or coat as you ride a bicycle in the rain.

My jacket was streaked in backspacle from the water coming off of my back bicycle tire after riding in the rain for hours.

After defiling your old lady’s ass doggie style, pull out your pud before you cum, and spray your jizz all over her lower back.

I love to back spackle on my old lady's tattoo.
