(noun) excessively large breast implants. Usually referenced as such when they are paired with revealing and tight fitting support clothing that pushes them up and out to cause them to form a nearly flat surface on top.
Most prevalent with larger women that choose to get DD+ breast implants to compensate/compliment their fuller figure.
