I always try to hype the act of someone misspelling something in a new and original way. For instance, “Are you on krak?” or “Stimulants not working?” or “Let’s eat vampire guano and paint”, but I think I am running out of words. Plus this stamp concrete (pronounce it the french way, like you are on ze board with it) is inexplicable in its simplicity. Dyslexic mirroring is the clinical term.
I cannot speak for the parties involved (did not prevent me in the past, though), but this sounds like the warmup for this particular sidewalk finishing was a double bill of Infected Mushroom and Hallucinogen.
Second round of misspelling was instigated by Bianca who was visiting and participating. She does not speak English, but she had noticed unusually large amount of misspelling I’d have missed. This street is called Accacia.
