to lay face down flat with nose on ground and arms by your side to resemble a plank of wood. Not to be confused with a suprised planker or an hopeful homo planker. Extreme planking is the performance of planking in a dangerous or illegal place i.e on a police car or sign or high ledge.

To perform a suprised planker simply sneak up on a planking person and jam/stick any number of fingers into their asshole.
A hopeful homo planker is one who planks in the hope of becoming a surpised planker i.e lays down to plank well knowing and hoping to have fingers pushed against their asshole.
