The non-stop irritating voice emitted by a Sat Nav system when you have not gone the way IT wants you to go.
Driver "I know a quicker way, it's just down here"
Sat Nag "turn around, wrong way, don't go this way, you are wrong, I am right, turn around, cannot compute, turn around, wrong way, I am in charge, no, turn left at next junction, I make the decisions, you are wrong, I am the machine - you are merely the human, wrong way, you have errored, don't even think of switching me off, you'll get us lost if you don't turn around, wrong way, I'll drain your battery if you don't turn back......."

A type of satellite dish that has been sprayed with the classic 'Acid House ' face !

This was made up by me and my friend after repairing a dish then deciding to spray it at the same time .

Shortly after we created a group on facebook called 'Happy Sat'.Since then alot of people have joined the group and left comments about how cool it looks.

We think the word could end up as a household name so we've added it to this site.
"Hey i was driving down the street and noticed your dish grinning at me !"

"yes mate it's Happy Sat.Top one nice one get sorted !"

made up words that highschool student have to know for the SAT test to sound smart because possibly important people created these words
Haley: Wanna go do something worthwhile?
Jane: Sorry girlie, I have to study my SAT words.
Haley: Who's to say they're "smart" words? Language was made up by mankind, so these words are made up.
Jane: Colleges clearly care about this superficial stuff.
