Klunen (pronounce the u sharp, as in Munich) is a Frisian
verb. It means walking on ice skates.
I doubt there is any other language that has a verb for such an
activity, although its meaning has been adopted into Dutch (Frisian is
spoken in Friesland, a province of The Netherlands).
To understand why one would ever come up such a verb, one must know
the tradition of (ice)skating, which is immensely popular all
throughout The Netherlands. People skate over long distances on the many
lakes, and canals that interconnect them. Frequently,
long distance skating tours are organized. For instance, the most
famous trip, the Elfstedentocht ("Eleven Cities Tour") stretches for
about 220 km/138 mi, all on "natural ice" (as opposed to man made ice of
skating rinks).
Oftentimes there are stretches where the ice is too thin to skate
safely; for instance the water under bridges does not freeze over
completely, and some canals are kept open for ships. In this case, the
skaters get off the ice, and walk (or if it's a competition
run) to a location where they can again enter the ice floor
safely.
It would take too much time to remove the skates, so they are kept
on. People put old carpets, wooden planks, or straw on the
ground to protect the skate blades.
