1.
The action of smiling while patting your cheeks with both hands lightly.

Origin: When your mouth is full of sushi that you really enjoy but you can't express your happiness so you find a nonvocal way to do it.

used for expressing any sort of happiness or glee when a single vocal expression just won't do.
Friend: Have you seen The Hobbit?
You: Oh my god Martin Freeman's faces makes me just... *sushiface*
