Redozerate
The act of falling asleep in class while sitting up-right. You then lose your balance while sleeping and start to fall to the side, waking you up and causing you to jerk back in an up-right position. This act is unintentionally repeated several times, resulting in a redozerate.
"Hey look at Jesse, he's totally redozerating."
"Yeah I fell into a redozerate once. It really sucked."
