SCRAMBLE
Scramble, or scrambling, refers to when a golfer misses the green-in-regulation but is still able to make par. Most of the time this occurs when a player's approach shot narrowly misses the green and then the player chips onto the green and one putts for par.
The term scramble is often confused with the term "up and down". The two are very similar except that in order to scramble the second stroke is always a par. When getting "up and down" the second stroke can be any score (birdie, par, bogie, etc.) and simple refers to taking two strokes to put the ball in the hole when close to the green.
This term is also confusing because there is a team format to playing golf that is referred to as a "scramble" but has nothing to do with scoring par while off the green.
SLICE
A type of shot in which the ball curves in the shape of a banana - starting out to the left of the target and then bending dramatically back to the right of the target (for a right-handed golfer; reverse for left-handed golfers). A slice is not played intentionally and usually sails way out of control and for right of the intended target.
Many golfers use this term interchangeably with the terms fade or push. This isn't necessarily correct as a push is a ball that goes on a straight trajectory just right of the target and a fade, although it does travel in this "banana" trajectory is usually played intentionally and does not sail out of control.
