googly boobs
n. The breast equivalent of googly eyes. Think of the eyes on a muppet: protruding spherical orbs that bounce and sway. Googly boobs are rather large (D-cup or larger), have just enough sag to allow them to sway back and forth pendulously, but aren't mushy enough to be described as jiggly.
When Brandee took the stage and doffed her top I was completely transfixed by her googly boobs.
