TIFU by accidentally identifying myself, my brand, and my company as "Sh*t Head"

A couple of months ago, Whiles brainstorming various names for a brand i had planned to build, I came up with the placeholder name of CeannCac. This name was only supposed to be a word used for building a website - one to use in titles, product descriptions, etc, and was to be changed later when I came up with an official brand. It was entirely a joke and was never to be seen or known by the general public. I was a self proclaimed ceanncac.

Those reading this who are Irish or from Ireland may recognize the translation of this word. "Ceann Cac" is in Irish, and translates directly to "Sh*t Head" in English. This is where my problem lies.

Due to issues with deadlines and finances, I never got around to changing this name. Still not seeing an issue with it at the time, i thought it would be interesting to see if this name would pass as i applied for sole proprietorship (for tax reasons) and registered the company name as CeannCac with the Irish government. Unfortunately, to my surprise, The name did infact pass.

Now, In every single letter that comes through my door, or any email I receive from the revenue commision, I get called a Sht Head. In any business transactions i make, i get called a Sht Head.

(Un)Fortunately, I began selling quickly. This was an issue. Anybody who owns my products are actively showing off that they are self proclaimed sh*t heads. I had not foreseen any sales until at least February of 2023.

Making matters worse, In my quest to build my own brands product, rather than sourcing other ones, I contacted our manufacturer. I brought forward my plan for a branded bike we could sell, One which would sell on a limited basis. What I recieved in return was an E-Bike with the words SH*T-HEAD plastered all over the bike, along the sides, on any labels, on the handlebars and on the display, even on the saddle.

TLDR; Because of my own corner cutting in creating a brand name, I am now forced to accept my own new identity as a sh*t head, and I'm forced to push this name on other people. The financial costs of changing this are too much for me to currently cover.
