This term can mean something is sticky.

Tacky, But how is this adjective used in other situations?

Jonathan, Did you buy your mom that tacky dress she wanted?

You mean the one with the stripes and polka dots and the enormous bow tie on the shoulder?

Yeah, I did.

Seems like she has her own idea about fashion.

If something is described as tacky, that means it is of poor quality or just shows bad taste.

A person can wear tacky clothes, tell attacking, joke or read a tacky romance novel.

Fortunately, I have never done attacking thing in my life, and that's English in a minute.
