This Conversation Is Over, also pronounced as Tee-see-yo. Used to let homothugs and Joes alike know that you are in control of an argument and are declaring it over.
Joe or huge homothug: why are you so mean to me?
Alpha Male: Because you are a mad gay, TCIO!!!

The acronym for "This Conversation Is Over". A great and courteous way to put finality on all your text messages, conversations, etc. A great new way to get the last word!
<Jules: txt to Claire> What time do you want to meet at the restaurant tonight?

<Claire: txt to Jules> 6:30 p.m. TCIO

Jules now knows that Claire is done with this conversation and will probably be away from her phone. The conversation has been given finality.
