Is it normal i want to change the spelling of some words?

And chocclit?

The spelling of Derp should be changed to whatever your name is.

I'm of the school of thought that wants some entire words in the English language changed. For example; 'Laugh' should change to 'Haha', 'She was hahaing at his jokes.', 'Don't haha at me.'

How droll, Mr Troll. 🙄

English spelling reform has a very long history, but 'happiness' is an example of a word in English that pretty much conforms to the rules of pronunciation, the only illogical bit being the additional 's' at the end.

For many centuries, there was no single, 'correct' way of spelling many words.

Many words in British English are currently spelled in the same way they were in Samuel Johnson's first first comprehensive dictionary of English in 1755, and he chose the 'correct' spelling based on what he thought was most common at that time. Some of those spellings made sense phonetically at the time, but pronunciation of the words has changed over the centuries. Other words were spelled in the same way they were in Latin or other non-English languages, in spite of the fact that the sounds assigned to letters in those languages were not the same as English.

When Noah Webster compiled the first dictionary of American English in 1828, he changed some words to be more phonetically logical, but he also deliberately chose spellings that were different from British spellings for nationalistic reasons. Fifty years after Independence, the USA was still trying to find a single identity and stop seeing itself as a collection of former British colonies.

Spelling in some languages is highly consistent; in Italian, for example, it's very easy to determine the pronunciation of a word from how it's spelled, and Italians would find the idea of having spelling bees in school absurd. Once a kid learns the sounds associated with the letters and a few special rules applying to two-letter combinations, if someone pronounces a word clearly and correctly, virtually every kid in the second year of primary school can spell it correctly.

Fun fact: "Ani ohev peen" is how you say "I like penis" in Hebrew. Unless you're female, in which case it's "ani ohevet peen". Here's the spelling:
אני אוהב פין
or
אני אוהבת פין

No

Hapenis sounds like one of those annoying short-form words that people love to hate.

NO!
