When you are so drunk that you buy a car and don't realise you did until the next day.
You did what!! Fuck you must have been buy car drunk!!!
Best buyed is when you go to best buy and you buy something and when you get out of the store you realize that you've been ripped off.
"God F#$@ I paid $2000 more than I should have... I've been best buyed."
example: get the fucking mug god damnit its a good mug you should really buy that mug
