What is a coffin-corner and how does one get into it in the pattern?

Jay frivolously used that well defined term completely wrong, presumably
just because it sounds good. (A tactic which some journalists use, too,
especially when they write about aviation...) You never get into the
coffin corner at pattern altitude.

The stall speed is constant with indicated airspeed, while Vne is
constant with true airspeed (acually, it decreases somewhat at high
altitudes). So there is a point, at very high altitudes, where Vs meets
Vne. This point is called the coffin corner, because you can't escape
from it (except by descending): You can't slow down (stall) nor
accelerate (Vne).
