We made up names for different parts. There were some chrome hand holds we had fun with. Some were 180 degrees and others were 90. We dubbed them a half nipple and quarter nipple. They'd been hearing me make fun of names like wench and vang boom, so the nipple didn't raise an eyebrow. At the end of the trip, one of the ladies made reference to grabbing the quarter nipple and the rest of us just died laughing.
