Belgian Sunburn

whilst most likely in missionary, the male will repeatedly smack his penis on the woman’s labia (or any second-party body part). Both parties can result having skin irritation/damage to the affected areas known as a Belgian Sunburn.

All he did was smack me with it. I think I have a Belgian Sunburn.

I cock smacked her so long and hard, I gave her a second degree Belgian Sunburn.
