The act of permanently destroying someone’s kneecaps. Often done with a firearm (as popularised in film and television), a baseball bat or lead pipe or other blunt instrument, or a power drill (often used in conjunction with a countersunk drill bit and popular with the IRA).
When the police heard the screaming, they knew that Shamus had been on the wrong end of an IRA kneecapping.

"Murray was kneecapping Rochester Jackie under the table, but Caleb didn't notice."

"If you all don't shut up I'm going to have to take out a .22 and start kneecapping."

What the Irish IRA and PIRA did when other drug dealers got in their way, they'd take a pistol and shoot him right in the back of the knee. This would shatter the knee, thus crippling the victim for life.

1. to shoot someone in the kneecap

2. to stifle someone or something
They were arrested after they were caught attempting to kneecap a homeless man and now face a trial for assault.
When a person is shot in both knees, rendering them unable to walk.

Used to be a favourite move for the IRA, but they gave up when orthopedics became good at putting knees back together.

Oh yeah, and a kneecap is the joint between your femur and shin bones..
"Hey man, I'll kneecap 'em for you!"
