A slapping motion with a closed or semi-closed fist. Often used by girls or really weak, pathetic guys trying to fight each other without using full force.

"My girlfriend slapunched me in the back because I told her to lose weight"

"Man, that hipster guy got slapunched right in the face, that will leave a mark"
