Brainfart

1. When someone knows how to do something right but at that instant he does it wrong even though he is pro at it.

2. When someone is thinking of saying/doing one thing but does the other.

*You are driving on the freeway and you knew you shouldve takin the 110N exit but you took the 110S for some reason*

Your friend: Dude I thought you knew you had to take the 110N
YOU: Ya I did, just had a freakin brainfart.

brainfart post

A post showing up on a social media page or group that is totally off topic, irrelevant or incoherent. It takes an average time of thirty seconds to click the link and read enough of it to realize it is a total waste of one's time. For example, on a group with 7,000 members, that one post has collectively stolen an hour of life from those people.

I just clicked on that post on the embroidery group and had to watch a brainfart post of a stupid video of a puppy puking up a sock! Did that guy really think the world of embroidery would be made better with that video??!!

Person A: No, I meant off... I had a brainfart.
