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!”

S-Avenue

John, a friend of mine, and I were playing a game called Splinter Cell Double Agent. We were in the first level, about halfway through, and hit a save point. We had a moral dilemma : Should we save, or not waste time, and forge through, courageously? I was in a pretty cocky mood, so I said "Saving is for wussies" and we plundered on. During the third section of the level (there are levels like 1-1, 1-2, 1-3, 1-4, and 1-5). We were on the third section, being 1-3. Having died several times after the save point, my friend quoted me saying "Saving is for wussies" after I said we should consider it. I saw the save come up, and I'm like "S-ave? What is S-Ave? Is it...South Avenue? Let's go to South Avenue!" Before we realized that it said save (cough cough), we accidently saved! Which means we are not wussies! And thus "S-Avenue" was born.

"Only wussies save, if you have confidence, you S-Avenue it up!"
