Table of Contents 

A complex chart consisting of dates, page numbers, topics, etc. that math and science teachers enjoy making you do. Your teacher will harp at you to write down the table of contents every day and threaten your grade if you don't. It is intended to be useful, but for the most part, it's not.

Teacher, glaring at your paper: Have you done the table of contents for today?
You: N-n-no?
Teacher: *eyebrows raise* You have to do the table of contents every day! Minus 10 classwork points.

puerto rican concentration camp

When a Puerto Rican man ejaculates such an exorbitant amount of semen into an object, leading to the murder of millions of would-be Puerto Rican children in one place.

This dude Hernan has dumped so many loads in his mattress it's like a Puerto Rican concentration camp.

concentric 

You will learn this in geometry.

Concentric means "sharing the same center". Con- = used multiple times, -Centric = center-related. (like cooperate: multiple people doing the same task)

So, it's like a dartboard or bullseye: the circles are all around the same point.

Something three-dimensional, like cylinders (water bottles, spray cans), may be coaxial.

The solar system is concentric. All the planets orbit the sun.

A properly set table has the bowls and plates concentric.
