amaillo comes from "Yellow" in spanish: amarillo. When i was a kid, in kinder, i had a friend who can't spell amarillo correctly, and he instead said "amaillo" from time to time. For some reason this fact got stucked in my mind for several years. Some years later i was creating my first email, i was thinking and thinking in someting original not related to my real name (because i always i've thought that is pretty boring and predictable use something like Pablo_Scovar1950 or so), but easy to remember...then, this fact about my friend come to my mind and i decided to use "amaillo" in the email, but for some reason amaillo was already took, so i had to use "amaillom" instead xD.
