Louche
However, the word comes from the Latin word luscus, meaning blind in one eye.
This gave rise to the French word meaning cross-eyed, and a figurative sense of shady or devious. Though the English
version dropped the sight-impaired meaning, it is still a great word with a
visual context to it.
Example
The famous detective, Columbo, paused at the door for a moment looking every bit the type of louche he had been assigned to find.
Example
"However louche Los Angeles' image may be, it remains a
puritanical city in a puritanical state. California caps the number of bar
licenses … at one for every 2,000 residents. That number hasn't changed since
1939…." — Josh Stephens, Los Angeles Times, April 9, 2015
