Scorpion Grand Slam

A term used to refer scorpions having sex.
"During sex, the male and female jerk and dance around, sometimes with their tails intertwined, with the male holding the female in his pincers. The a male scorpion ejaculates on the ground and pulls the female so her sex organ touches the sperm. After she takes in the sperm the couple usually disengage and go their separate ways." -factsanddetails.com
