The Metro Spectrum is the term that defines the full range of metro-sexual traits typically reflected in a man's hygiene, fashion choices and grooming habits.
In a sentence:
"My friend tends to be a little on the high end of the Metro-Spectrum."
On the low end of the Metro Spectrum are men who don't seem too concerned with outward appearances. In the middle are men who enjoy nice shoes and fitted shirts. Things like trimmed arm hair and a shaved chest are found on the high end.
