Toe Strike
Contact made toward the far end of the clubface (away from the shaft) instead of the center.
Usually causes a weaker shot that leaks toward the left, via draw spin from gear effect, and a distinctly different vibration through the hands than a center strike.

Fat Shot (Chunk)
The club strikes the ground before the ball, losing speed and distance.
Thin Shot (Skulled)
Contact happens too high on the ball, sending it low and hot with no height.
Shank
The ball contacts the hosel instead of the clubface and shoots hard sideways.
Heel Strike
Contact made near the shaft end of the clubface instead of the center, a milder cousin of a shank.
Sweet Spot
The small area on the clubface (roughly the center) that produces the most efficient, powerful contact.
Pured (Flush)
Slang for a shot struck perfectly out of the center of the clubface, it usually feels like almost nothing in the hands.
