A week or two ago my daughter started using the word "mahoosive" to mean "very big", "huge" or "massive". She seems to have caught this from her school friends. A quick search on Google reveals the following variant spellings:
- Mahoosive - 19,700 hits
- Mahusive - 5,620 hits
- Mahousive - 1,300 hits
I presume that this first appeared as an embellishment of "massive". The earliest appearance in Google Groups is in a post from 1999, so it is not an entirely new coinage. I suppose it could have been around a lot longer.
