bastardise 

To make a bastard doesn't necessarily have to refer to people. Giving a legitimate word a new meaning could be bastardising the word. Basically, it's butchering the English language. See orphaned. If you have an idea, and someone takes the idea, changes it around and gives it new meaning, that's bastardising. If you design a newsletter, for instance, and someone else takes over and keeps part of your design but applies elements that don't match up with yours, that's bastardising. You get the drift.

Henry, how do you like the newsletter now that Sue's been doing it for a year?

I'd like it better if she hadn't bastardised my design.

Well, how do you like urbandictionary.com?

Half the people putting stuff up there just bastardise the language.

Bastardisation

That fucking silly bastard derick nobcheese illustrates perfectly the way the english language endures bastardisation with his shit explanation of said word:

Atomic Kitten have bastardisation
a song again!
Apple have bastardisation
microsoft, or tried to.

See? The silly fucking dumb cunt.

Bastardisation, the process of, is a corrupted copy of a given original.

derick nobcheese is a bastardisation of a human being.
