plethora effect 

The "plethora effect" is when kids use words in college application or SAT essays that sound good but they don't really know the meaning of. Sometimes they'll accidentally use thme as words that sound similar but have completely different meanings (for example, accidentally saying homeliness instead of homelessness) or sometimes they'll just be totally wrong. It was given the name a few years ago when someone decided that "plethora" was a 'good SAT word' and everyone started using it in college essays, much to the chagrin of the people who actually read the things. It's basically a result of kids prepping for the SAT and college process too much. (Starting SAT review books in middle school, taking tons of Princeton Review classes, etc.) Can sometimes be helped with the use of spellcheck.

Admissions person 1: "Look at this, this girl's essay is about how 'fragile and venerable' she was as a middle schooler, and how much she's grown."

Admissions person 2: "That's the plethora effect for you..."

Plethoremotion

The feeling of having every emotion known to man, simultaneously occurring inside you, happiness to sadness to fear, the whole shebang. Originates from the feeling one has after watching an episode of Doctor Who. The most common facial expression that can be used to identify Plethoremotion is the " :O " face and at times, even the "jizz in my pants" face. It can be clearly defined by thinking of one million million million million million roller coasters of emotion, that are on fire and filled with liquid nitrogen flying off the rails in concert and falling into a pit of flowers and skeletons while fireworks explode all around them, accompanied by dramatic music played solely on the piano. Similar feelings are also, the one where you can't feel your heart any more, or it feels like there is a hole in its place.

"awh man, i just sat through a Doctor Who marathon...I'm just so...so...plethoremotional"

plethora 

noun.

1. an excessive amount.

2. A lot.

This word is primarily used with great imprecision by inarticulate, pretentious college undergraduates who wish to express no more than "a lot," but want to do it with as many syllables and as annoyingly as possible.

Unbearable undergraduate#1: I just drank a plethora of coffee so I can study for the test today.
Unbearable Undergraduate#2: Dude, me too. I hope there's not a plethora of questions.

plethora 

A lot

I was at a funeral and someone came up to me asking for permission to say a word at the front. I said of course and he stood up to say one word, ‘plethora’. I said ‘thankyou, it means a lot’
