1. A particularly aesthetically pleasing pair of breasts.
2. Breasts which receive much attention because they are exceedingly delightful.
3. A nice rack.
4. (singular) qualititty
It should be noted that qualititties are not discriminatory: it matters not if they are large or small, nor does the color matter. Both original and surgically altered can be qualititties; it is basely solely on the wowza factor. Also, this is meant to be complimentary not pejorative.
"Wowza. Look at the qualititties on that woman over there!"
The word 'quality' is often mis-used to mean 'of good quality' although its true meaning is neutral (good quality, poor quality, etc.)
'Qualitay' is a deliberate misspelling and mis-pronunciation of the word 'quality'. It is used jokingly to mean 'good' -- in other words it absorbs the incorrect meaning assigned by many people to 'quality'.
