wedge means one of the corner portion of a triangle. You can imagine that attributes of a mesh (color, normal texture coords) can be stored there in a way that can allow to manage easily discontinuities and smooth variations. In this way a face store the colors for his three vertices independently.

I think the first widely use of this term is in this paper:

Hoppe, Hugues. "New quadric metric for simplifying meshes with appearance attributes." Proceedings Visualization'99 (Cat. No. 99CB37067). IEEE, 1999. (PDF)
