Ahah, well!!! I think you pronounce the s a bit more towards the sch- or sh- instead of ...sss ? It's not a big difference, you show this only with words like so and you do it just the tiny bit that it's enough to be peculiar and amazing. Hopefully it won't offend you, but i guess your speech mannerism kind of reminds me of Bane from the Batman movie? I think it's really cool!
