as a general
descriptor for men's underwear regardless of whether the garment in question is a pair of briefs, boxer shorts, etc. It's important to note that one cannot "go commando" and say they have
a "nut-hut"; however, the defintion could be expanded to include athletic supporters (i.e. "jockstraps")
Rather than saying
"It's hot out today and my balls are rather moist," one now has the option
of stating "It's so hot today there's a sweat lodge
in my nut-hut." This usage is equally valid whether the speaker is wearing
underwear and/or an athletic supporter.
