Top definition
To become a hoss, specifically, to occupy more space as one becomes older. Characterized by a general thickening and/or shortening of the neck along with general physique ballooning. Accelerated by red meat, beer and too much maxing and relaxing. Hossification may be noticed at: high school reunions, family gatherings, annual meetings or any event that brings you into contact with people who you have not seen in awhile.

Note: Hossification does not necessarily entail merely getting fat
Dude did you see Doug at the bar? He has really hossified recently. Two more years and I'd say his hossification is complete.
