Some long-term listerners to his MATI podcast claim that he's sexually attracted to the fat dirty girls he talks about, and given how openly ecstasic he is to talk about them I wouldn't discard it.
Null sounds like a relative calmed individual most of the time, callous, uncaring even, but as soon as he talks about chantal or chelse he lightens up and sounds excited like a child in a candy store.
I don't know if you can call them "lolcows" in their own right, but Josh was attracted by some of his female forum posters and he was catfished by a troll who told him she was a wealthy teenage girl that could get him a 100k job because her CEO father just spoiled her that much.
One of the reasons why Josh hangs around Beauty Parlor so much is because he's trying to get connections, a job and, ultimately, a marriage, through the forum.
What a charmer.
