Those that are in love with their horses
and prefer interaction and intimacy with their horses
than with actual people. Also are snooty
and inevitably annoy all those around them

"Oh did you see the Horse person's status about HORSES
on Facebook? Not very surprising..."
"Bobby, why don't you date Sue?"
"Because dad, Sue's family is full of horse people"
