Combining the actions of - whether intentionally or not - opening the eyes as wide as one can, whilst displaying a large, open smile, showing as many teeth as possible. It is meant to be embarrassing - whether for the person caught with the Blaise face, or the person the Blaise face is directed to.

Often used as an expletive when displaying
the expression.
Wow, I totally had a Blaise face in this picture.
