"Slapping five and giving propers has turned into an absolute given following every foul shot in NBA and college basketball games. Teammates are all about letting the foul shooter know how proud of them they are because they have made (or even missed) a 15 foot shot without any defenders in their face. A strange twist to free throw congratulations has come about in recent seasons though. Foul shooters have started seeking out propers from their teammates. Its come to the point where the league should outlaw it."
