sex board 

A piece of wood (usually a 4x4) used to lift the FUPA, or pannus, of an obese female, or occasionally male, for easier access to the genitalia for sex.

He: hey baby, wanna have sex?
She: yeah, just let me get my sex board so you can get it in.

extreme sexboarding 

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?"
