This style is common across many internet words.
Examples include.

Grammar Explanation
Grammar makes the answer easy.
So belongs to standard English grammar.
It performs several grammatical jobs.
- Adverb.
- Conjunction.
- Pronoun in certain expressions.
- Adjective in limited cases.
Because it serves multiple grammatical functions, dictionaries recognize it as a complete English word.
Soo has no grammatical role.
It simply replaces so in informal writing for stylistic effect.
Grammar books, dictionaries, teachers, editors, and style guides all recommend using so in standard English.
Spelling Rule
English does not form emphasis by changing a word’s spelling.
Instead, writers create emphasis with punctuation, stronger vocabulary, or sentence structure.
For example.
Correct.
I was so surprised.
I was incredibly surprised.
I was extremely surprised.
Informal.
I was sooo surprised.
Professional writers almost always choose better vocabulary instead of adding extra letters.
