Period

Periods are mysterious creatures that live in the minds of cool people who use it even if they have no idea what it means. They just think it's cool. Period.

The period (also known as a full stop, especially in British English) is a punctuation mark (. )

primarily used to indicate the end of a sentence. It appears as a single dot on the bottom line of the text,

without a space and it comes immediately after the last word of the sentence.
