Pat: "No, No, Ann! When someone feels that way, you need to get them some chicken noodle soup."

Elaine: "Well, I'm going to feed the bird so-"

Pat: "NO, NO, ELAINE! For a bird like this, you only feed it three to four times a day and you want to give it honey."

Ray : "I'm going to run out and get some tools to-"

Pat : "Ray, that's rubbish. To fix a bicycle, you have to use old dirty tools. New tools don't get the job done these day. It's the old fashioned kind that will get the job done."

Know-It-All

Someone who thinks they know everything that is to be known. They argue about things that they have no knowledge about. They either act like they know or they really believe they know what they are talking about on any given subject. They are arrogant and believe they are always right. See arrogant, hard-headed
I know what a know-it-all is because I am one.

know it all 

pejorative One who makes it appear as if they're an expert on a subject while there are also signals (subtly or blatantly noticeable) that this person doesn't know very much on the subject or at least as much as they're acting like they do on the subject; pretending to have much knowledge on a subject matter
(Note: there are countless ways to seem knowledgeable on a subject as by behaving correctively and correcting people all the time, giving unwanted advice, expressing opinions as fact, not accepting advice or information from others, etc., but when there are also indicators that one doesn't know what they're talking about, they're considered a know it all or engaging in know it all behavior)

"Even though I'm only fifteen and I've never held a job before I want you to listen to me carefully; on your interview, if you're not sitting cross legged, they won't hire you. If you don't nod, they won't hire you. Employers hate when you don't wear a tie. Companies these days aren't into what's on your application. Employers these days are real into the whole look aspect of it all. Take it from me," said my know it all son before I handed him his schoolbag and replied, "Shut up and go to school, dear!"

I found it shocking that some know it all bum out on the street was telling me how to handle my taxes the right way.

I try very hard not to seem like a know it all when discussing scientific matters; I provide evidence and back up what I'm saying and explain to others of my college experience in the field. That way, people regard me as knowledgeable and not a know it all.

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.
