Daft in the first place to say "drywall", as all walls are dry, unless
made of mud, which is still dry once it's set.

Lath and plaster with horse hair is a wet wall....


They say two by four as well ....

I always thought they called it SheetRock ?.

SheetRock is a brand name.

It's known regionally by different names, gypboard, drywall, sheetrock,
blueboard/greenboard (mold resistant), etc.
