Sex takes place (male or female), but instead of regular sex, both participants ride on snowboards down a hill or trail while doing it, preferably at high extreme speeds. Additional partners may be involved as well.
"Dude, did you see that threesome extreme sexboarding down the trail last night?"
"Yeah man, that guys jizz was left in the snow and I fell right on it."
"Did it taste good?"

When one is struck suddenly with the urge to go #2 in an awkward setting and needs to find a bathroom immediately.
After the sorority wings eating contest I had to go extreme-o so badly but there were too many people in the sorority house and I had to go across the street to the freshman dorm to find an empty bathroom.
