When your having sex with two or more women on the roof of a home missionary style. However, before you cum you flip the women over and jizz on there backs instead. This way the skeet will fill the scratches left behind by the shingles, and possibly prevent infection.
"Hey yo Jake, those two girls that i shingle decked last night ended up in the hospital because there backs burnt too much..."
