つー事 as a sentence starter


What does it mean when people start sentences with つー事? Is it an abbreviation
of something else?  
Two examples of such are:

「つー」 is the common contracted form of 「という」 and furthermore, of 「っていう」.

In the order of formality, it is 「という」、「っていう」 and 「（っ）つー」. Learners should
know that among the three, 「（っ）つー」 borders on slang. DO NOT use it with your
teacher, boss, etc.

Needless to say, 「つー」 is pronounced exactly the same as 「つう」. (That is only if
you are pronouncing 「つう」 correctly in a single syllable.)

All of these forms are quotative in function and meaning, referring to what
has already been discussed, implied or has been shared as common knowledge
between the speaker and the listener.

> 「つーことで」 means "and so", "therefore", etc. when it comes at the beginning of
> a sentence. It is also sometimes used in colloquial speech as a
> conversation-ending phrase meaning "That is all I have to say." In that
> case, it is said just before saying good-bye.
>
> 「つーことは」 comes at the beginning of a sentence and it means "So, that means
> ~~" or "If that is the case".
