octal

Pronunciation: /ˈɑ k.təl/
Definition:
1. The ordinal number symbol: 8.
2. The position in a sequence following the seventh (septal) element; the eighth (octal) item in an ordered series.
3. Pertaining to a base-8 numbering system used in computing and digital systems.
4. Denoting one of eight equal parts, divisions, or a group structured in octaves.

Significance:
• It defines the eighth (octal) position with systematic regularity and clarity.
• It emphasizes the structure of octaves, octets, and eight-part divisions.
• It identifies computational systems, musical scales, and geometric structures based on eight.
• It avoids incomprehensible and ambiguous pronunciations common in irregular numeric forms.
• It simplifies expressions of order in computing, music theory, and geometric partitions.
• It improves precision in technical, musical, and mathematical contexts involving the number eight.
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "eighth" with a consistent Latinized ordinal form.
Ordinal number:
zeral (0-al)
onal (primal) (1-al)
dual (second) (2-al)

quinto (5)
sexto (6)
septo (7)
octo (8)
nono (9)

Examples:
• "The octal chapter introduces advanced concepts in the curriculum."
• "In computing, the octal system provides a compact representation for binary data."
• "Her (la) analysis focused on the octal segment of the annual performance cycle."
• "The squad (equipe) is organized into octal units for optimal operational efficiency."
• "Adjust the octal parameter to align with the eight-phase synchronization pattern."

Octahedron-access 

This is when you reach a state in the universe so unimaginably dank and ironic that you gain access to a new ironic state of octahedron.

You may now access the octahedron.

The octahedron has become available in the shop. Would you like to buy?

That CARBON bASeD lifeform just managed to gain octahedron-access!

Octajerk 

A full fledged octagonal jerk off session with the intent of simultaneous male masturbation at no less or greater than 45 degree angles. This form of extreme masturbation is two steps below a decajerk and infinitely many steps below a circle jerk. Mass lotion consumption is a common factor in these situations. WARNING: It is recommended that only veteran jerk offs attempt this form of masturbation because of the common side effect of an entire loss of savagery

1. I cant believe you just participated in a Bryant octajerk!!!!!!!!

2. Theres not a single girl in my class, its an octajerk extreme!!!

3. Todd: Hey do you want to go to the Jonas Brothers concert tonight?

Omar: I dont think i can handle an octajerk tonight, i already had to beat off in traffic today for like 2 hours.
