A person who is lurking from a distance. To make things awkward by disappearing randomly and randomly showing up. Usually scaring people when returning from sketching off. Often the friend in a group who's just kinda around. Mostly the third wheel in a group. Can also be a couple who don't want to be watched while hooking up

Used in snowboarding and skiiing to describe an unsafe/unpredictable/hazzardous park, urban or backcountry feature.

Also used in both sports to describe a peice of terrain/snow pack that is considered unpredictable and likely to avalanche.
" the transition on that kicker was super sketchy but buddy managed to stomp the landing anyway."

"We made a couple of turns but the snow was really sketchy and could easily have avalanched...so we got the hell outta there."
