To grab the bumper of a vehicle and be pulled. The classic definition would be performed in shoes on ice, but seasonal and regional variations may be done on dry land in roller skates. Exceedingly fun and dangerous.

to stick one's head up out of a cubicle to look at something. The term comes from prairie dogs, who burrow in the ground. In a field with prairie dogs, if there's a loud noise, typically many of them will pop their heads up out of the ground.
John trashed his monitor in a fit of rage and all the prairie dogs popped up for a look.
