An advertisement (television or otherwise) that, rather than causing a desire for a product, induces a repulsion from said product due to the use of popular entertainers such as Michael Winner and/or Dale Winton(eg.).

A really sad advert.
That advert for pile cream really sucks. What a sadvert.

An advert that is predictable and boring, and just plain saaad.
"Did you see the latest toothpaste commercial?"
"Yeah, what a sadvert."
