look up any word, like plopping:
 
1.
The act of decorating your house, or any other area, in a fall theme. Fallifying usually occurs during the months of September or October, and usually involves lots of pumpkins and/or cornucopias.
Kathy was thankful that fall break was coing up because she desperately needed to fallify her house.
