nipple brooch

A large, pasty-like metal ornament used to adorn a pierced nipple.

Few people thought it was by accident that Mr. Timberlake's hand snaked across Ms. Jackson's torso as he reached the lyric, "I'll have you naked by the end of this song," and tore off one bustier cup, releasing a breast partly obscured by a sunburst-shaped nipple brooch.
