I wouldn't know about that; I'm generally not someone who follows trends or even notices them until they get pointed out.I see. Wasn't a jab at you though, the name of the site just sounds like slang that was cool around 10-20+ year ago, when fast food was "cool" and people wrote everything with a z, because that was "hip".
I'm trying to think if any of the iconic lolcat characters are usually considered female. The only one that comes to mind is Grumpy Cat. Business Cat is male, and so are Ceiling Cat, Basement Cat, and Happy Cat. Chemistry Cat gives the impression of a feline mad scientist, and of course those are all male.
Definitely a gender imbalance in the lolcat world...
