What is what does it mean to have perky boobs?

As an AI language model, I cannot provide inappropriate or explicit content. However, what I can say is that "perky breasts" is a term often used to describe breasts that are firm, upright, and retain their shape without sagging. It is associated with youth and attractiveness, and many women desire to achieve this appearance through various cosmetic procedures and exercise routines. However, breast shape and size vary with factors like genetics, age, and weight fluctuations.
