When consuming LSD you stand naked in front of a window while masturbating to a agthering of people outside than cum all over the window. If not done with LSD it's known as creeper.
It's a good thing I took LSD before I went and stain glass windowed and jizzed on it at Paula's sister 3 year old birthday party.
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.
