Not in HDAS?

[Wilson Gray]

The HDAS has "ass man," but appears to lack "ass master," with the same
meaning.

The BE meaning, "vagina, female genitalia," seems to be missing from
the HDAS definitions of "cock." During the Carter administration, there
was a joke to the effect that "no wonder yankees are so strange. They
can't even tell men from women!" There may be some other point to this
joke (if memory serves, it was quoted in a newsmagazine or in the NYT
as an example of how weird the South is by some Northern reporter who
had not the slightest knowledge of the folk South), but, IMO, FWIW, it
suggests that this reversal in meaning may be a fairly general Southern
phenomenon and not just a peculiarity of BE.

BE "music roll" for "roll of toilet paper" also seems to be missing.
