Must be “tighty” because they sure aren’t tidy. Back in the day when I wore briefs they usually had skid-marks also know as grass stains. Don’t usually have that with boxer shorts.

The only “tidy” whities are briefs that have been folded and placed in one’s underwear drawer.

The proper term is “tightie” as representative of the snug fit and rhyme with the diminutive of white.

It’s ‘tighty’. The contrast is to boxers which are loose fitting. Whomever used ‘tidy’ is mishearing it. Like me everytime Elton John sings about wanting Tony Danza to hold him close.

@Entropy funny reference to Tony Danza… I will never hear that song again without thinking of your interpretation.

According to Merriam Webster it is tighty-whitey…meaning snug white underpants for men : white briefs. The plural is whities preferred over whiteys.

Depends on whether you want snug or neat.

^^ How about neatly snug??? ;-}

If the briefs are clean and neatly put away they are tidy.

If the briefs are simply snug fitting, they are tighty.
