Periodt

Usually used at the end of a sentence or rant to express the end of a conversation, no questions asked. It can so be used as a way to agree to a certain statement. The 'T' at the end is supposed enunciated, with the 'd' being silent, or not said at all.

In texting, the amount of 'T''s added at the end is equal to how much one agrees with a specific topic.

Emily: "Samantha hooked up with Brad last night!"
Sarah: "Periodt!"

"If your man doesn't clean the house at all, break up with him periodt."

"Omg Ariana is coming out with a new album!!!"
"PERIODTTTTTTTT"
