Cuckface 

Descriptor pertaining to the awkward nature of Nu-male faces and expressions, especially in photography of both candid and premeditated respects.

Anon-chan: "Why do all Nu-males make this same dumbass smile, it's gay as hell."

Anon-kun: "I heard it's called cuckface."

Anon-senpai: "They look extremely neurotic and anxious behind those fake smiles. You can see it in their eyes: it's all a show. This upbeat, spontaneous facade they put up is so forced and dishonest."

Cuckface 

On December 26th, 2017 an anonymous 4chan user speculated that open-mouthed smiles were a signal of submission and being "lower in the social ladder" according to “research on non-human primates.” Another user replied that the smile should be called a "cuckface" as a spin on the duckface facial expression.

Since then, it has steadily trickled into online communities under a variety of aliases: “Cuckface,” “Nu-Male Smile,” and “Soylent Grin.”

Now, Soy is a food that extremist, misogynistic subcultures have linked with weakness, feminism, and beta status. There’s also the debunked claim that soy products increase men’s estrogen levels to the point of growing man boobs. Put these conspiracies into a virtual blender and you get an unimpressive slang term to insult any male you think is a snowflake for smiling too big in his selfies. Some men have taken it a step further, claiming Soy Face is the sign of a cuck or a simp.

If you guessed the Soy Boy and subsequent Soy Face memes were concocted by basement-dwelling shitposters, you’d be correct.

Basement dwelling shitposter (proud MRA or any other subset of the manosphere) : Men who identify themselves as feminists are all soyboy beta cucks. Just look at their miserable "Cuckface". Ain't no real man supports feminism.

Cockface McSmellass 

not just your normal cockface, one who goes above and beyond the call of "duty" to bring new heights and new meaning to the insult of cockface. Examples include pissing AND vomiting on a friends couch when extremely intoxicated, fucking a friend's sister AND girlfriend within the same relative time period, and flunking out of two separate college's after having been awarded and athletic scholarship twice.

Dude 1: So you were pretty wasted last night?
Cockface McSmellass: Yup, pissed and vomited all over myself and Mike's couch.
Dude 1: Truly a Cockface McSmellass.

Yo dude you mind if I bang your sister??
Sorry man Cockface McSmellass over there already beat you to it.

Cockface McSmellass is at it again folks.
