Example:
Example 1: It is just a weak malleable metal that fuses the wires in the cable to the metal hardware input port to create a connection flow, and normally an engineer designs an external support to hold them together, part of which is that thick plastic area at the end of the cable where it connects to the hardware input unit; which is the device connector and its own external support; but on this shitty Chinese Display Port (DP) cable that was entirely decorational... The actual wire fuse took place in the middle of the box that was supposed to be the hardware input unit, which was actually just decorational as well... It has only the DP connector and not the rest of the device that supports the strength of it, with nothing but copperfoil (10x weaker than tinfoil or paper) wrapped around it and a big plastic shell popped together around the whole thing to make it look like something that was engineered properly from the outside while on the inside being designed at the engineering level I had at 10 years old.

Example 2:

Person 1 says, "The phone case I ordered has gears on it."
Person 2 says, "Wow, are they functional?"
Person 1 says, "No, they're just decorational."

Example:
The decor in the family room is just awful!

Example:
Anne is having a decoring party this sat, are you gonna be there?

Example:
“have some decorism about yourself”

Example:
eric decorated the bathroom at players

Example:
I decorated the books in the library.

Example:
A school of fish, a murder a crows, a flock of seagulls, a decor of poofs.

Example:
Girl 1: That hat is so pretty! Are the zippers on it functional?

Girl 2: No, they're just decorational.

Example:
Man, my sugar daddy wants me to visit him in his office every week, but I want money to pay for my clothes so I have to be decorous.
