A term used to describe titties that are usually bigger than a pomegranate but smaller than a watermelon. Keep in mind that in this case, the tits are NOT saggy. The term "deflated" just means they are squishier than usual.
Person A: Did you hear about Hendrik's new girlfriend? I heard she has deflated soccer ball tits.

Person B: What a lucky bastard! Those sort of tits are the best!
Person A: No way! The best tits are the inverted inflated infusiblenesses tits!
