Snowboard terms, defined.

Riding with your non-dominant foot leading instead of your natural stance. If you normally ride left-foot-forward (regular), switch means riding right-foot-forward - and vice versa. It feels foreign at first but is essential for landing tricks and all-round board control.

Your natural stance on the board. Regular means riding with your left foot forward, goofy means riding with your right foot forward. Neither is better - it's simply which way feels natural, like being left- or right-handed.

The two edges of your snowboard. The heelside edge runs under your heels, the toeside edge under your toes. Almost everything on a snowboard - stopping, turning, carving - comes down to controlling which edge is in the snow and how much pressure you put on it.

Describes the direction of a rotation or approach, usually abbreviated FS and BS (as in FS 180, BS 360). Frontside means your chest opens toward the direction of travel (or the obstacle) first; backside means your back leads. A frontside 180 for a regular rider rotates counter-clockwise. The terms come from surfing and skateboarding and stick to every spin and rail trick.

The rounded crest of a jump landing - the hill right after the kicker, where the flat deck rolls over into the downslope. Coming up short and landing on the knuckle feels like hitting flat ground, so you aim to clear it and touch down on the slope past it. Riders also session knuckles on purpose: bouncing tricks off them ("knuckle hucks") is a lower-consequence way to play with pop and rotations.
