Roderdingling

Verb: To define an awkward way of making up silly jokes.
Adjective: To define a bizarre feel of a person, mostly dumb.

Anyways, this guy is roderdingling my jokes, and he is still doing it!

Idotiataing End

To define the first word, it meant “stupid” (I guess you knew that from the first 5 misspelled letters, from the first word.)

So the whole meaning is “Stupid end” (You really can use it for someone who ended something using a very idiotic way)
Some individuals will use it as a fun way to describe a character whose personality is mostly not smart. And, if you are one of them, you are all wrong. You all noticed the word “End” behind the first word.

You all can use the word “End” in a way you used it to define the word “end” and it's tenses.”
Pro-tip: Never ever use the word “Idotiataing” in any tense, it will sound very bad, and I warned you, I mean, you can use it as an adverb only.

The scene is ending badly. This is a idotiataing end.

Objunctional

Defining a very shitty opposite meaning of "Malfunctional"
Basically, this means that a machinery has issued a fault (Most likely a false signal) to the main engine.

For example:
"This machine of always objunctional, it will often signal fire alarms for no reason."
