meretricious

One of those words I've learned forty times and forgotten forty-one.

From onelook.com:

Quick definitions:

meretricious:

adjective: (archaic) like or relating to a prostitute (Example: "Meretricious relationships")
adjective: based on pretense; deceptively pleasing (Example: "Meretricious praise")
adjective: tastelessly showy (Example: "A meretricious yet stylish book")

Maybe, finally having something bawdy to hook the meaning to, I can retain it this time. Let it never be said that I don't make a good straight man.
