Oops, I forgot: plicykling is a combination of bicycling with picking up litter merging the Swedish verbs plocka upp (pick up) and cykling (bicycling) giving us the new Swedish verb plicykling. Based off of the portmanteau plogging the currently trending word is pliking which means hiking and picking up AND biking and picking up. I think biking and picking up should have its own word.
