slang for a woman who's had too many facelifts and her eyes are pulled back like an Egyptian cat. When viewed from the front, it appears there is a corset behind her head that has been made too snug.
This came about while watching Susan Lucci's most recent infomercial on face cream. I said, it looks like she has an Eye Corset! Her eyes were so taut they couldn't even close- like an Egyptian Hieroglyph!
