To have long and intense sexual intercourse which can be compared to hard training in gym, running, biking, swimming etc related sports.
Go out on Saturday, pull a girl and take her home. Have some sex with her. Next morning have some more sex and give her good ride for 1-2 hours until you are exhausted. This is sportsfucking. It can also happen any give day and hour, doesn't necessarily have to be on Sunday.
