Mojack 

Slang term for Icelander, especially a rural one--popular term among US military personnel stationed in Iceland during WWII. Origin unknown.

That Mojack insisted vehemently that his cow was sick because of being sexually assaulted by our soldiers, but after our camp veterinarian diagnosed and treated her for a common bovine ailment, she made a full recovery; then the Mojack gave us some cheese to make amends.

Mofackle

When cursing is unacceptable because you're either at church or at a business meeting or among mixed company or you want your underage kids to use a curse word and the verb or noun mother fucker needs to be used you can you mofackle instead.

Confession to Priest: Forgive me father, for i have been a bad mofackle!

In anger: You are on dumb mofackle!

Son: Daddy that mother fucker almost hit us running that red light!

Dad: I know son but please use mofackle instead!
