When a person wears a low cut shirt, tank top, bikini, etc. exposing one's neck & upper torso revealing their clavicles, often but not only, in a sensual way.
"Yo dude, Lindsay has some sweet clavage goin on."

"Yeah man, you got some nice clavage yourself."

Get the clavage mug.
The exposure of a person's clavicle bone by wearing a scoop neck or V-neck shirt.
I have no breasts so I wear shirts that expose my clavage.
