The shittiest of people to ever exist, and if they have any sort of problem, they'll make sure everyone knows. You can't have any sort of private life around a Katie, they've just got to get involved and somehow ruin everything. You're in a relationship? Katie just had to get involved and ruin it. Got a friendship? Katie just had to get involved and ruin it.

Stay away from the Katie's, especially if they own more than two cats.
Looks like a lesbian, owns more than two cats and has a thing for copying other people's music tastes and styles? That's a Katie.

Katie is a very lovable and loyal person that knows how to get what she wants. Furthermore does she face the grind to get there even if it means to lick the asshole of that one old neighbour at the first day of moving to another city in terms of education.

A Katie is also that kind of girl you get a handjob of under an old, moist blanket at an afghan 30th birthday after you vomitted baklava all over the persian handmade carpet in the living room.
"Hey look over there, what a self concious 3rd degree Katie!"

When you meet a Katie, you know you've found a friend for life. Katies are the best kind of people. Usually blonde, gorgeous locks of hair which anyone would be jealous of. Katies are also notoriously bad at Mario Kart, picking the worst possible combinations of vehicles yet she always stays smiling and never complains how everyone always beats her. Katies tend to fall in love with short people, and really struggle when it comes to heartbreak. Katies are also often very tall, my guess would be around 5'10. You can usually tell if someone is a Katie because she'll be wearing the most amazing outfits that only she could pull off because of how pretty she is. Katies are the best kind of people :)
You see that girl over there? She's definitely a Katie.
