Not a typo, but as a waiter I told a woman about our Cedar Seared Caesar Salad. Except I didn't say Caesar, I said Semen.
Cedar Seared Semen Salad. Oof.
Edit: Just realized the tongue twister was actually worse. It was Cedar seared salmon, Caesar salad. Whoever chose that as a menu item was some sort of sadist.
This reminds me of my practice French oral exam at school, so not a typo but still:
As part of the conversation my teacher asked what sort of things I liked to read, and I decided to talk about a then popular technology magazine called T3.
"T trois" sounds rather like "Tais toi" (shut up), and she was a bit taken aback!
Thankfully though we learned not to use that in the real exam.
The worst typo I ever made was texting my friend who is a Black woman that she needed a bigger TV. Unfortunately the b & n are right next to each other on the keyboard and I wrote one of the most offensive words ever. Even though it was an innocent mistake, I apologized profusely to her.
My family name is Carvalho (oak). I asked my then 8 years old son to sign his passport and he wrote “Caralho”. I’ll let you search that on Google with the safe search OFF.
When i was in primary school I was searching images of different types of pasta on the school computer for a project and accidentally typed 'pene' instead of 'penne'
One time I copy pasted a horrific NSFW subreddit to my sister that I was making fun of the existence of to a friend just before. That count? It did not fit into the discussion we were having at all and she was horrified. I can't remember the name of it now but it was like "fapcaves" or something where people literally post up pictures of their huge disgusting masterbation stations they make.
Not mine but from a colleague: years ago on a very big signboard in the center of our city, promoting a gig with a very special guest at the time (still very good tho), tech house dj Satoshi Tomiie, he wrote Satoshit Omiie...
I saw this from somewhere else, a person was in a multiplayer, and in the chat they were trying to type "edits", but made some other typo in that, which auto-corrected to "drugs" before they sent it. So the message turned to "Tbh I make drugs."
My workplace has a program that will pay for your college courses, so I signed up for a certification course at CUNY. I had to fill out a bunch of paperwork for my workplace and list the college multiple times. Well, the letter T is right next to the letter Y on the keyboard, so I accidentally put CUNT instead of CUNY in one spot. Thank God my boss was cool and just thought it was hilarious.
