Smearing is a technique used in rock climbing to help haul yourself up the cliff face. Essentially, one finds an incline or divot, or any slightly lessened angle of the face your attempting to conquer. Then you press the tips of your toes slightly above where you want you're foot to stick, press into and down on the rock, bending your toes back and smearing them against the unyielding stone. The only thing left to do then is utter a small prayer to the gods of friction and sticky rubber, and move on towards the next hold.
