You're having a Facebook conversation with a joke account you created for your kettle!? This disturbs me; it's tantamount to Teiganism.

Lyn Hershman's creation of Roberta Breitmore would today be referred to as 'Teiganism', but in fact predated the invention of the term by forty years.

The funniest girl you will ever meet, but don't let that distract you from her beauty. She doesn't give a fuck about society, but cares about you. She is secretly a tiger in the bedroom and has a knack for swimming :)
emmi: I met an awesome girl today :)
mum: She must be a Teigan!

Known as the most beautifulest, self-centered (and occasionally stuck up), bitchiest, yet the most funnest and funniest person you will ever meet in your damn life. Most commonly to think that she's better then others, but doesn't like to brag about it. But knows it's definitely true. One of the best kissers you could find. Commonly to be known as the "toy all guys enjoy" and admired by all genders. Even aliens perhaps. Befriend a teigan. THEN WORSHIP AT HER FEET.

Teigan is one of the nicest people you will ever meet. She is caring, kind and knows when something is up... She is the best swimmer and she knows it ;) :)
But other than that she is my bestie and she knows it. And she knows that i will always be here for her and she can talk to me about anything... And even when we grow old we (hopefully) will meet up all the time and drink tea. Like posh old women :D
So i will get her to look it up this arvo and she will see this and now something i have wrote is on the interent yaya.. but back to teigan.. She is just awesome... I dont know what i would do without her and if i wouldn't of met her last year, i wouldnt of even of known she existed.
But cheers EIGAN!! :) :) xxx
I cant think of an example... :/ Teigan

should be known as annoying but is loved by everyone. Her insecurities get the best of her even though people tell her she is beautiful. Is a bitch at times but she´ll still love you.
guy: I met this girl at the party last night, she´s so bitchy
