Hexakosioihexekontahexaphobia

Fear of the number 666, or the "Number of the Beast."

I can't pronounce hexakosioihexekontahexaphobia. Too lazy to try.

Hexacontaenneagon

A hexacontaenneagon or hexacontanonagon is a polygon with 69 sides.
It's also known as a sexagon as well as a fuckagon.

The sum of all interior angles is 12,060 degrees.
One interior angle is 174.78 degrees.
One exterior angle is 5.21 degrees.

Because 69 isn't a Fermat prime nor a power of 2 or 3, a regular hexacontaenneagon is not constructible, not even with the use of compass + straight edge nor an angle trisector, as the number of sides is neither a product of distinct Pierpont primes.

The hexacontaenneagon is the weirdest and most vulgar polygon.

Hexamryiakaipentachiliapentahectokaitriacontakaiheptagon

an obscure shape that looks very similar to a circle, but actually only has 65537 sides and is still a polygon, with the only mentions being on wikipedia and a OneMinuteThings video

guy 1: what is your favorite shape
guy with hippopotomonstrosesquippedaliophobia: a rectangle probably
guy 1: my personal favorite shape is the hexamryiakaipentachiliapentahectokaitriacontakaiheptagon
guy with hippopotomonstrosesquippedaliophobia: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

sulfur hexafluoride

A very dense, inert, non-toxic gas that is much heavier than air and used in the electrical industry as an insulating gas. If you inhale it, it would make your voice sound like Satan, i.e. really deep. This is because sound travels through this gas slower than it does through air.

When the science teacher demonstrated how sound travels differently through different gasses by inhaling helium and sulfur hexafluoride respectfully, he began to talk like a chipmunk and then like Darth Vader.

Justin Bieber inhaling sulfur hexafluoride would probably result in his voice sounding like a normal maturing teenage boy's voice, rather than like a little girl's.

hexadecimal

The format for a number written in base-16 instead of base-10 (decimal). Commonly used in computing or electronic fields, since each digit in a hexadecimal number is trivially converted (by humans or machines) into 4 bits with a table. A number in base-10 is more difficult to convert into binary, requiring repeated division by 2.

When writing a hexadecimal number, for digits greater than '9' convention dictates use of the first 6 letters of the alphabet. So the digits are:
0 1 2 3 4 5 6 7 8 9 A B C D E F

The value of the popular magic number DEADBEEF when converted from hexadecimal to decimal is 3735928559.

Silver Hexafluorophosphate

Silver hexafluorophosphate is a commonly encountered reagent in inorganic and organometallic chemistry. It is commonly used to replace halide ligands with the weakly coordinating hexafluorophosphate anion. The chemical formula is AgPF6 and has a Off-white powder appearance.

Person 1: "Did you know that Silver hexafluorophosphate can act as an oxidant, forming silver metal as a by-product?"
Person 2: "Who?"
Person 1: "Who what?"
Person 2: "Cares."
