A material may be classified as rippable, marginally rippable or non-rippable.

In the mine area the overlying argillites and shales contain permafrost, but this ground is rippable where frozen and does not present a problem.

Lefts, Rights, and A-frames could be directed from this pump design providing for rippable surf and barrel rides.

But sometimes I pick up the knee, which was lent to me by a helpful orthopedic nurse, and turn it this way and that, trying to decide whether this particular arrangement of bones and cartilage and stretchable, rippable attachment cords is the stupidest or most elegant engineering design I've ever seen.
