I think you mean ludicrous instead of lubricious, just fyi.
Here's the excerpt from dictionary.com
------
lubricious [loo-brish-uh s] adjective
arousing or expressive of sexual desire; lustful; lecherous
------It kinda defeats the purpose of using the word if no one else understands what it means :)
I understand fine.
So "shifty" could be what they were going for, but my sense of the other two words in definition 2 suggests that it's not quite accurate to use that sense of shifty.
