A threesome involving a woman spitting a load of cum from one dude onto the other guy.
More descriptive Explanation: Two gentlemen and one woman. The woman is giving one man a fellatio, while the other man starts complaining or isn't interested. Upon ejaculation into the woman's mouth, she then turns around to spit it at the other man. Bam, you're hit by a hail storm.

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
