Originally yes, but I'd say the definition evolved to be an adjective that describes someone who is manly, badass, hotblooded, etc. There exist badass and manly women in anime, just like there are plenty of pussy men. Cornelia imo is a genuine example of a GAR female.
Kino is not, and I don't understand how in the hell she could win against 11/11 or Alucard. That's just a fucking joke. Not bashing Kino or anything(she's a great character), but she isn't nearly as GAR as they are. She has the occasional displays of badass skill, she is hard as fuck, but she isn't outwardly manly or hotblooded in any way. She's a tomboy with mad gun skills.
