mash potato mouth

The action in which one tries to speak and a fully formed sentence is not formed. There are fragments and random words. The person is intently trying to form a sentence and make a point, but the sentence is incomprehensible. There is usually an utter of words and the spew of grunts and/ or the word uhh. This action is usually accompanied by a blank stare or glazed look.

I went to talk to him, but he started mash potato mouthing everywhere. He is real hard to talk to.

Mash Tag

Not to be confused with (#) "Hash Tag", the (+) Mash Tag was created by Oklahoma native Paige Stiner to be used in the place of Twitter's "Hash Tag" on Facebook in 2011. It can be used when you are specifically talking about one topic and you want to make it known, it can also be used to add comedy or emphasis to a comment made. While a Hash Tag makes things searchable on Twitter, the Mash Tag has no real function. It is said to be a trend started to convince Facebook users to stop using Hash Tags where they did not originate.

That was quite a win for Oklahoma!
