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!
