Perhaps Bla^Bla? You might call this a "Blaplex", analogous to googolplex, the first proposed definition of which was "one, followed by writing zeroes until you get tired", so Blaplex would be writing nonsense until you get tired. Sadly, sundialsvc4 seems tireless.

Update: Hey, maybe we could get the Unicode Consortium to define a raised-^Bla symbol along the lines of the © ® ™ ℠ symbols. sundialsvc4, who is addicted to typographic engrossment, would then have the ideal, appropriate symbol with which to pepper his posts.
