When a device (mostly electronic) is dropped on the floor either intentionally or unintenionally which results in the device working better than before, then the device is said to be "channed".
My cell phone used to drop calls all the time till it got channed. Now it works like a charm.
Person A: how was that party last night dude?
Person B: dont ask me I was blackie channed, probally made a fool out of myself.
Person A:nice, you were probally that kid.
