I need a word, a clean word or phrase to express "interfere with" or "manipulate" that captures a certain depth of disapproval of some extremes of self-imposition on procedures or texts that ought to be inviolable, or at least untouchable by one of the pay-grade doing the meddling.
"Mess with" is altogether too mild.
"Mangle" or "tamper with" don't convey the presumptuousness and vanity of putting ones own stamp on that which does not belong to one; nor the speaker's contempt for that presumption and impatience at being expected either to not notice or to complacently accept, (inherent in various obscene or scatological phrases, "f*** with," "s**** with," or "d*** around with.")
An apt metaphor would be that of a dog marking, in the manner of all dogs, the various hydrants, trees and territories, of which the dog despite, her incontinent bravado, has not the ownership.
Well, having conjured up that picture, I guess I worked the anger out of my system and can go back to work. (Righteous anger? maybe... but don't be too sure, Scelata.)
