The comic depicts the adventures of Peräsmies, a Finnish superhero and a parody of Superman. The name Peräsmies literally means "Butt Man" and is a play off Teräsmies ("Steel man") which is the Finnish name for Superman. The "official" English name of Peräsmies, according to Kokkila, is "Phartman", although "Pooperman" might better capture the essence of the original pun.
