knee sliders

Formed pieces of hard plastic or compressed leather incorporated onto motorcycle roadracing suits to protect the suit leather from damage while cornering. The sliders are attached to the leather suit towards the outside and just below the knee area of each leg, usually with velcro.
Expert motorcycle roadracers must replace their knee sliders quite often.

ass clown

1. One whose stupidity and/or ineptitude exceeds the descriptive potential of both the terms ass and clown in isolation, and in so doing demands to be referred to as the conjugate of the two. 2. A male who engages in homosexual behaviors. See butthole surfer

knee dragging

Term used to describe the act of motorcycle roadracing, in which the rider's inside knee often comes in contact with the track surface while cornering and with the motorcycle leaned over. Knee dragging is more likely when the rider is hanging off of the motorcycle - a technique used to minimize the lean angle of the machine and thereby maximize tire traction. For this purpose, leather roadracing suits incorporate knee pucks (also known as knee sliders) on the outside of each leg, just below the knee.
Billy was knee dragging all over Road Atlanta last weekend.

high side

Motorcycle roadracing term used to describe a crash in which the bike is leaned over while cornering and flips back up towards the outside (i.e. the high side). A high side usually occurs when rear wheel traction is suddenly lost and the rider's panic causes him to abruptyl close (chop) the throttle. As a result, the rear wheel suddenly and forcefully regains traction, violently flipping the bike away from the direction of lean and throwing the rider skyward. Most racing injuries occur as a result of a high side since the rider has much further to fall.

The flip side of this (no pun intended) is a low side crash. These crashes are usually minor since the rider falls off much closer to the ground.
That clueless squid lost the rear halfway through Turn 7, chopped the throttle and high sided his brand new, chromed out R1 into the hay bales.

lean angle

Motorcycle roadracing term for the angle between the center plane of the motorcycle and the vertical plane. The more the motorcycle is leaned over, the greater the lean angle. High lean angles are necessary when cornering a motorcycle at high velocity, but too great a lean angle results in loss of traction and often a crash. Riders employ a technique called hanging off in order to alter the rider-motorcycle system's center of mass and thereby minimize the lean angle necessary to negotiate a corner at a given velocity.
Establishing and maintaining the correct amount of lean angle is a balancing act that a motorcycle roadracer must master in order to ride fast.

percolating butt coffee

A form of intestinal distress brought on by retention of water in the bowels and resulting in butt coffee of varying density and consistency. Characterized by periodic gurgling and/or rumbling noises emanating from the lower abdominal region, and frequently accompanied by cramps. Usually caused by ingestion of bacterial pathogens.

center of mass

The point in a system of bodies or an extended body at which the mass of the system may be considered to be concentrated and at which external forces may be considered to be applied. Also called barycenter or centroid.
In general, an object with a lower center of mass is more stable. This explains why weebles wobble but they don't fall down.
