To me, tacky is silly, fun, out of the ordinary...something folks like to poke fun at....in a good kind of way! :)

I once lived in an apartment building where my neighbor specialized in tacky things....he had a classic Santa head that hangs in the window with a blinky nose...and between our two apartments, he hung a collection of black velvet paintings...with the bull fighter taking center stage...OF COURSE!
