Apparently "G8" when pronounced in Chinese sounds like slang for "penis". [0] Canon had a popular line of cameras named G1/G2 etc - they skipped from G7 to G9. [1] HP also had servers with model names and generations that were also abbreviated as Gx, so HP ProLiant DL380p G7. They changed their naming convention to Genx when the 8th generation came up, so Gen8 instead of G8.

(Fun side story - apparently HP names their servers this way for government procurement contracts. So the contract can be written specifying a "HP DL380p server" and HP can supply whatever the latest generation is. Even if it shares nothing in common with the previous generation other than a name.)
