Please tell me that this is NOT a word - lawsuited

[The Blue Flower]

2. I was a technical editor for 35 years

The first time I saw 'architected' in a report, I struck it out and asked for a correction from the author. I was told that it was a common verb in his field. It was supposed to mean the same as 'designed'. I once worked at the Lockheed Skunk Works in Burbank and found myself at a desk in a room with six other editors. We were editing reports from all over the company to be submitted to the feds to justify funding. The conversations about usages that the engineers came up with were monumental and memorable. The one that sticks with me after 30 years was whether database was one word or two. Microsoft published a dictionary-sized glossary to standardize the language of computers and programming. It changed constantly. So in your case, the correct word would be 'sued'. 'Lawsuited' is just ignorant. But you never know. If enough people start saying it, it could quietly enter the language and end up in your Merriam-Webster's.
