Unofficial medical acronym for a person who is about to die. The acronym stands for "Circling The Drain". Using this acronym on a medical report, under certain circumstances, can get one fired instantaneously. (There is an official use for "CTD": it really stands for "Carpal Tunnel Decompression".)
Ms. Kendricks, you're fired! You're the one who wrote "CTD" on the coroner's report!
