Legend has it that in the dark ages, when DEC (Digital Equipment Corp) licensed ARM from Acorn for their StrongARM processors, they took Arm's testing toolkit and ran it to find issues with their processor.
Now, ARM was a tiny division and only had developed their tools for strictly internal usage. It was never supposed to go to some huge and professional enterprise like DEC.
So when the DEC engineering team ran the tester, It shouted a SHIFTER FUCKED error right at them lmfao
