[Vocabulary] Skiing terms (cork)

[maiabulela]

Dear all,

I came across veru difficult skiing terms and i'm in bad need of help.

The commentator saying stuff and I coudn't get it at all. The episode is about "European Freeski Open"

The commentator saying things like:
270 on - 270 on switch up - 450 on 450 out - Switch Cork 900 – Double Cork 10 mute - 900 mute

Switch 270 on 270 out - 180 on 360 out - 450 on - 270 on 450 out - Bio 900 mute - Switch 1080 tail - Switch Double Cork 10 mute

270 Disaster - Alley Oop 180 360 out - 270 in Pretzel 270 out - Switch Lip Underflip 450 out - Left Double 1080 Mute Grab - Right 900 Reverse Mute Grab - Switch Double 1260 Mute Grab

1- First, do those numbers refer to angles?? ALL of it?
2- The terms "Double cork" - "switch cork" - "mute" - "mute grab"... Is there any definition, glossary or link... anything that might help.

I really hope it's simpler than one what I think. The problem is that things gets repeated the whole episode!:shock:

Thanks in advance.
