The
pedestrian crosswalk is when two people are having sex and a third party person walks over or on the backs of the people during intercourse.
This position is best done
outside in the streets.
It is believed homeless people invented this sexual position. Either them, or a group of drunk
frat boys.
John and Jane had
no money for a
hotel room so they had sex in the middle of a busy sidewalk and ending up doing it
pedestrian crosswalk style.
