80s 10
A girl who was very hot, 10 of 10, in the 1980s, but looking at pictures of her now she would be considered a 7 at best by today's standards - note 1. this terminology can be transferred to any other time period (50s, 60s, 70s, etc.) - note 2. the woman cannot exceed a 7 of 10 in hotness or the terminology is invalid.
Taylor: Man I expected the lead singer from Blondie to be way hotter than she is

Zack: yeah but you know she was sooo hot in the 80s

Taylor: total 80s 10
