3.
- An adjective of extreme power.
Means one who is dimwitted, a dumbshit, stoopid-head, wacked out in the mind, or just plain retarded.
- It can also act as a unit of measurement, and adding the suffix 'ly' to the end of the original word can do so.

- Derived from the 'Monte Online Facility System' (MOFS) of New South Wales Catholic school, Monte Sant' Angelo, a.k.a MSA, the word mofus was created with just the addition of a U to make the new word seem more plausable to the Australian Language.
