1. To successfully pull off some sort of a prank involving calling another person's cell phone, usually from a masked number (for instance, via relay).

2. To be struck by a cell phone, preferably in the face, in such a forceful manner that one could only it as describe as being owned.
"Hey, I just relayed Dan, from work, and left him a sweet message."
"What'd you say?"
"I had the operator tell him I was from the corporate office, and if he wanted a promotion then he needs to help me wipe my butt, and then I layed down a nice freestyle about my favorite vegetables."
"Man, that's ridiculous. He'll know it was you."
"No way, I totally cellphowned him."
