Peer Pressure

From the world of skiing: somebody who skis is a skier.
On seeing (spiritual or prophetic): somebody who sees is a seer.
About going pee: somebody who pees is a peer.

Yesterday for our kindergardener's last day of school, the class went to the park. One of the kids started daring and urging the others to pee in the bushes. Our son did. Now, that's what you call peer pressure.
