Definition of "overstuffed"

[…] Mr. [John "Walking"] Stewart used to observe, that the deplorable effect of too much book learning is to deprive man of self-examination, through an over-stuffed memory, which prevents the exercise of the faculties of imagination, judgment, and reflection, and to make conscience depend on the will of others, and not on self-knowledge; […]

He was so round and fat that his stomach looked like an overstuffed dumpling, with his waistcoat for a crust, and his mouth was drawn down at the corners in a plaintive way, which contrasted oddly with the fun that twinkled in his eyes.

It may be asked why soak with warm water at all, on this theory? Why not soak with oil and tallow exclusively? The answer is because the oil, under such circumstances, will "slough" off, but if water not exceeding 110 degrees in heat be applied it will drive the oil from the surface and modify that greasy feeling and untidy appearance which attaches to over stuffed leather.

On paper, [Ice Age:] Continental Drift boasts a jaw-dropping voice cast, including but not limited to Jennifer Lopez, Patrick Stewart, Wanda Sykes, Aziz Ansari, Simon Pegg, Nick Frost, Nicki Minaj, Drake, and Alan Tudyk. But in practice, the overstuffed ensemble leaves the cast no room to distinguish themselves, and directors Steve Martino and Michael Thurmeier don't seem interested in coaxing performances that might render their money stars less identifiable.

We furnished our first nest with castoffs. Friends alerted us to an overstuffed chair that someone on the far side of the ballpark was, outrageously, throwing out. No three dishes matched. We owned one big-ticket item: a clock radio. Every morning, we woke to the broadcast calls of birds.
