Soyfie
A portmanteau of 'Selfie' and 'soy'. Usually used to denote a selfie in which a male, often nerdy, progressive, or mildly flamboyant has their mouth opened in a perfectly round and slightly puckered circle.
You can find a soyfie on the social media of said people, often affiliated with Sequel-Era Star Wars or the Geek and Sundry YouTube channel. Travis McElroy, although not necessarily affiliated with the above, is the principal example of one who takes "soyfies".
"Bruh, why are Chuck Wendig and Wil Wheaton making that weird face?"
"Bruh, didn't you know? Soyfies are a trend in modern geek culture."
