butterfly doors 

Butterfly doors are doors that open horizontally, and then move slightly outward so that the side of the door is facing the front of the car. These are NOT to be confused with scissor style doors like those found on a lamborghini. An example of butterfly doors can be seen on the Ferrari P 4/5

Damn son, your chevy has them butterfly doors?
