THE word used as a replacement word for any other word of the same syllables. Used mostly due to its palletable sounds and verbal deliverence.
For example 'I cannot find the bloody odenboast!' When as talking, the word that was intended (such as 'carving knife') evaded the speaker!
Can also be used in many rhymes such as 'Can you hear my odenboast, Nooo O, Nooo O, Can you hear my Odenboast, I can't hear an Odenboast'
