You can't "lock" something that doesn't exist.

[Lacan]

And I did one. Haven't found a single link saying it's a race locked to one gender. All of it was classes/jobs locked to one gender.

It refers to anything that is locked to one gender. It really isn't that complicated. Don't get why people are so hung up on word choice all of a sudden. People referred to miqote and roes as genderlocked back in 1.0 as well and there wasn't a raging debate over it. Think it was even used to describe Mithra and Galka too. You guys just want to argue semantics.
