Word fart 

When you are trying to talk and you keep stuttering and saying the wrong thing so you have to stop and start the sentence again

Person 1: "It's a god, gog, dog, blah blah blah (pause)... let me start over , it's a good idea"

Person 2: "that's started off as a word fart"

To say something you don't really mean.

I'm so sorry!, sometimes word farts just come out for no reason.

When you say something that causes the room to clear out, as if a toot was just dropped.

We were standing in Mark's office when he dropped a wordfart about his last prostate exam.
