A human male displays the Nümale Grimace (aka the Soylent Grin, the Moneyshot Face, the Human Gloryhole):

The soyboy lives in a constant state of fear and automatic deference to his dominant superiors, which include the women in his life. He spends his waking hours gesturing his submission to anyone who will tolerate his company. If no one is available to accept his submission, he submits to himself, in a final act of plaintive onanism that ends with his seed mixed in edamame crumbs and spilt 120 minute IPA.
