Screamer :
  1. A long and loud fall.
  2. A nylon webbing structure consisting of one large loop sewn in multiple places to make a shorter length. The stitch-points are intentionally sewn with less than maximum possible strength. The screamer is attached with carabiners between an anchor point, particularly one of dubious strength, and the climber. In the event of a fall the stitching of the sewn sections is designed to rip apart, absorbing some of the fall energy and decelerating the climber, thereby reducing the overall shock load on the dubious anchor. Screamer is a brand name of Yates Mountaineering.

Short fixing: A traditionally-belayed lead climber reaches a new belay station, creates an anchor, tying the lead rope off to the anchor. The climber then switches over to self-belaying and continues to climb. Meanwhile the second climber ascends the fixed rope using ascenders (aka Jugging) and cleans the pitch. When the second reaches the belay, he or she anchors in and starts to belay the leader in the traditional way again. When the leader reaches the next belay the process is repeated.
Side pull : A hold that needs to be gripped with a sideways pull towards the body.
Simulclimbing : A technique where both climbers move simultaneously upward with the leader placing protection which the second removes as they advance.

Sit and spin : A method of starting a rappel from a cliff edge, accomplished by sitting with legs over the edge and then spinning around to face the cliff while planting feet on the face.

 : A style of climbing where form, technical (or gymnastic) ability and strength are more emphasized over exploration, self-reliance and the exhilaration of the inherent dangers involved in the sport. Sport climbing routes tend to be well protected with pre-placed bolt-anchors and lends itself well to competitive climbing.
Spotting : A method of protection commonly used during bouldering or before the leader has placed a piece of protection. The spotter stands beneath the climber, ready to absorb the energy of a fall and direct him away from any hazards.
Sprag : A type of hand position where the fingers and thumb are opposed.
Spraying : Giving unwanted - and unasked-for - beta to a fellow climber. Also, excessive, overly prominent, or boorish proclamation of one's own (often exaggerated) skills or exploits.

Stick clip : A long stick on the end of which a climber can affix a quickdraw. It allows the climber to clip a quickdraw to the first bolt on a sport climb while still standing on the ground. This is especially useful if the first bolt is high up, and out of the comfort zone of the climber. A stick clip can be bought or easily made by attaching a quickdraw to a stick with a rubber band.
