Usage of the word rolling is also trademarked and limited. You forgot about wheels that do not roll. Can't use that either.
You may have found some people using wheels for rolling. They should be frowned upon, given extra-intimate pat-downs, blackmailed, arrested anyway, made fun of before trial, given a long unfair trail, be non-lethally tortured because they might know other "rollers" and later executed for being a danger to the state beyond any help after which his familly will be billed for all expenses (and exported).
