- interjection sometimes offensive, religious people will use this curse instead of so they will not take the Lords name in vain. It is also a Pop-culture reference to the comic book 'Superman' which took the allegory of Moses and Jesus Christ from the Bible and made Clark Kent's superhero alter-ego.
A Roman Catholic School Girl would shout out "Clark Kent on a cross!" after stubbing her toe, so not to offend a preist or a nun, much.
