If this LLLL ended in other letters, like fomm or fopp or fogg, it would just look like a mistake, an acronym or typo. But with the double zz that is cleared up, due to the precedence of fuzz and fizz being real words. Even Fozzy Bear from the Muppets just adds a 'y' to this, so you're on safe ground for this sounding like a real word.
4-letter words that sound like something - and especially that sound like something funny, cool, rad, etc., are becoming in huge demand, for branding and for erecting interesting/exciting/entertaining businesses and websites around.
Even for a less-cool LLLL that sounded like something I'd ask low xxx; you may not get much out of a domainer for this name, maybe somewhere xx to low xxx at most - but get it visible to some end users, like in the 'entertainment' category at Sedo for example, and see if there's any interest. Personally, I'd think an end user, with a fun zany site in mind, would REALLY like this name; then you could start valuating it according to what kinds of corps/people show interest.
It's such an unusual name that could swing many ways, I'd just leave a 'make offer' tag on it in the beginning, rather than trying to rummage out a value...
Nice name. Fun, versatile, short, abundantly Kool, and brandable.
