Wednesday Legs are not pretty! They describe a pair of frail and skinny pins on the verge of breaking.
Wednesday = When is they (going to break!)

Get the wednesday legs mug.
A phrase used to describe a really attractive pair of legs on a woman, so that the woman who is being described does not know that you are talking about her legs (i.e. it is a code system).

More specifically, this is used to rate legs in a covert way - the rating system running from Sunday to Saturday, with "Sunday legs" being too thin and "Saturday legs" being too fat - hence "Wednesday legs" (the mid-point of the week) are just right.

N.B. When rating legs it is important to note that no two pairs of wednesday legs will ever be the same - there is no preset size or dimensions, it is simply how the legs are in proportion to the woman.
(Attractive woman in front)
Man 1: Look at those wednesday's!
Man 2: I dunno, they look more like mid-tuesday's to me...
(Attractive woman walks away, out of earshot)
Man 1: She had some damn nice wednesday legs.
