Oh, so if i state that my character [b]"clenches his mighty anus with great force"[/b] as a defense prep, his [b]"clenched mighty anus"[/b] will nullify Ysolda's infinite hatred spell or any other sort of unprepped magics?

Not a good move. Knowing how often characters get attacked there, your character's butt would be shredded and could no longer clench his way to victory.
