When you give a list of three attributes, people tend assume the salient features are common for all three or different for all three. The attributes you gave were obese, poor hygiene, and unshaved. Two of these, obese and poor hygiene, are problematic for reasons other than simple lack of social acceptance, and people thus feel more confident calling them “gross”—for which they were also primed by your use of the term in it’s other sense.
As I see it: no, you didn’t say it, but I completely understand why they heard it.
