What does RPC’d Mean?

For the life of me I can’t find this one. Here’s the backstory:
A highly intelligent student (notice the sarcasm) at my daughter’s middle school brought a knife to school not too long ago and showed it around. A student who is actually smart (and a friend of my daughter’s) told a teacher about it and the kid has been suspended.
That same day, the rocket scientist sent a vaguely threatening text to my daughter saying he knew she was the one who got him “RPC’d.” After that was cleared up, I wondered what RPC meant. I know it’s a suspension but what do those damn three letters meeeeeean?
