Chalk board 

The act of accidentally sneezing on your smack. Creating a large white cloud that eventually settles on the surface it was originally on.

Yo dawg. Kevin and I we're gonna do some booger sugar last night but he sneezed and made a chalk board.

Often sunonimous with getting off on two or more female partners as they lie nude and one cums all over their stomachs, leaving a sticky white substance. Then proceeds to write his first name on one girl and last name on the other.

Those two bitches got chalk boarded last night. See my name is on their stomachs.
