Your 4's and 5's are my 6's and 7's

A girl you think is in the 4-5 level of hotness is actually a 6-7 to someone else.

"That girl isn't hot."

"Well, your 4's and 5's are my 6's and 7's.

6's and 7's 

The phrase, to be at 6's and 7's implies that you are at a loss, or in a state of ineptitude where you cannot reliably take acton.

The saying originates from a situation in 1327 and relates to the Guilds of Tradesmen in the City of London. The Merchant Taylors and the Skinners were founded within a few days of each other, five other Guilds having already received their charters. The age of each Guild dictated its position in the Lord Mayor's procession. The Merchant Taylors and the Skinners argued for fifty years as to which should go sixth in the procession. In the end, Sir Robert Billesden, the current Lord Mayor, decreed that they should take it in turns to go sixth and seventh.

Their defense was in utter shambles. They couldn't do anything right. They were at 6's and 7's.
