Where did the usage of bury in "bury a jumper" come from?
Many times in sports, the lingo is very, very complicated if you don't know the slang of the place and very idiomatic English.
A jumper stands for a jump shot in basketball.
Bury here means to shove it or push into or through the basket so that it cannot not go through it.
Bury a jumper: execute a clean jump shot.
(Also, in sports lingo, when you win over an opponent, you can be said to bury them).
