big ol' contraction, all of which are often used in typical contractions, mostly to be cutesy, I'll concede.
Would not have = wouldn't've, for example.
I also often write colloquially spoken contractions that aren't typically written.
This one = this'n, for example.
Somehow, in a real email, I managed to contract both of them.
This one would not have = this'n'dn't've.
I'm kind of proud of that.
