"terminally" = utterly; extraordinarily

[Jonathan Lighter]

Not in OED but common in humorous and semi-humorous speech for a long time
(30 years?).

The first time I've encountered it used with a straight face:

2008  Brian Hanley  _Planning for Conflict in the Twenty-First Century_
(Greenwood) 126: Another illustration of the terminally insidious impact on
French society of the Great War.

Professor Hanley, who holds an M. Litt. from Oxford University, teaches at
the U.S. Air Force Academy.
