Scerious is pronouced as though you are saying serious with the letter K in front of the first E.Scerious is a word only to be used in the most solome and serious situations. It means Serious but the word also indicates if your friend is lying you get to whoop his ass. It is kinda like putting Ferreal and Serious into one word.
I am Scerious I Banged your Girl Friend.
Dude, are you scerious.
