S I On

Pronunciation: /ˌɛs.aɪ.ˈɒn/

Used to emphasise that a statement is serious and not made in jest; a stronger form of promise or assurance, typically employed when ordinary affirmations such as “I swear” or “I promise” might be doubted.

Blend of “Seriously on”, developed as a convention for distinguishing genuine statements from jokes.
“You actually got the job?”

Yes, S I On, I did!”
