Kenny Cone = a cone that gets hit repeatedly. On a big course Kenny is typically a poor course design. On small lots it's often just a cone designed to control speeds - people try to avoid the necessary slow down then Kenny gets killed over and over again.
Pinch Point = a corner or element that drivers thinks they should be able to drive faster. Because they can't drive it at the speed they want then it must be a bad course design.
Brian Cone = stays in the trailer until my patience runs out
