Hunt and Peck Typer 

Literally the worst insult you can imagine. Saying this will end someone's career in one blow. They (and their bloodline) will have no employment opportunities and will likely die from the roast. Saying this is the easiest way to induce mass genocide.

"Hey man, I bought some bepis, do you--"
"STFU, you're just a hunt and peck typer."
