Plain

Dull.

The plain girl was plain and bossy, not colorful, exciting and fun.

Uncanny Plains

A cognitive and emotional discomfort triggered by speech or behavior that is superficially normal but subtly fails to follow expected human logic, timing, or cooperation—especially in dialogue.

When the voice assistant kept dodging my question with slightly off replies, I got that creepy Uncanny Plains feeling.

plain-sewing

According to the Oxford Dictionaries: "(2) Slang , a sexual activity of homosexuals involving mutual masturbation." According to Fintan O'Toole's review of Edward Mendelson's "Complete Works of W.H. Auden" (vols. V and VI) in the New York Review of Books of Oct. 22, 2015, the expression was used by W.H. Auden in his essay on J.R. Ackerley's memoir, "My Father and Myself". Auden made it into the OED with two citations (for first use in print) from this essay of his, for "plain-sewing" and for "Princeton-First-Year", which means frottage, or rubbing, generally. Using the hyphen better distinguishes the expression from its main usage, that is, to refer to simple sewing.

Bruce and Wayne started with just a little plain-sewing in the shower, but then quickly threw themselves into bed and gave it everything they had.

Peter Plain

The most boring person you've ever met.

Person 1: I went on a Tinder date yesterday.
Person 2: Oh really? How was it?
Person 1: He was a real Peter Plain.

Fort Plain, Ny

Wants to be a hood so bad. Drugs and alcohol are a common activity, kids born there develop facial hair by age 3, the water is greatly polluted with lead and aids, and it is only a matter of time until all then buildings collapse in in themselves. People who live there are often referred on as “ pants” because they are full of shit 24/7.

If you want to live in Fort Plain, Ny, Don’t.

Plain

Someone that thinks cursing (expressing negative feelings in words that don't sound sweet) and anything not G rated or Disneyfied is inappropriate for everyone (just like walking around with no mask and hand sanitizer is inappropriate for everyone to plain adolescent souls). The kind of person that would hire a hitman to kill somebody then still talk about other people doing bad or inappropriate things.

Though he/she was always a clown, he/she was never really funny, because he/she was always a plain Mickey Mouse Club kind of clown. He/she claimed that people respected him/her, but the reality was that nobody owed him/her anything, including respect.

Person A : You sound like an idiot!!!
Person B :I'm not an idiot, get it together!!!
