A form of social torture by showing your friends in the Midwest or on the East Coast pictures of sunny Southern California while they are stuck inside during yet another snowstorm.
I spent most of the morning at work "snowboarding" the guys in the Chicago office.
Or
Cheri was sorry she choose a school back East, having been "snowboarded" by her friends at UCLA.
To be awesome on the snow, to gain accreditation for almost super nautral feats on snow or ice. The equivalent of street cred but in cold climates. Snow cred is given out to extreme sportsmen and women who perform outrageous tricks and skills in: Snowboarding, Ice biking, Snowmobiling... etc. It is acknowledgement of the achievements and strides in snow sports.
Man that was some sick sick air you got there, gotta give you snow cred for that.
