That's the exact problem.
If you aren't 100% certain 100% of your audience understands what you're saying, you have 0 reason to go out on a limb.
The fact that the slang cannot be written in an instantly recognizable way is why it will never catch on. If you can't text it, meme it, snapchat it, or otherwise disseminate it amongst your posse, your posse will use other terminology. Should some break-out cultural phenomenon lay claim to it, we might all be subjected to it... but we will then all be subjected to whatever fucked-up syntax was first to popularity (pwning, hodling).
