- refers to a culture of people with rear wheel drive vehicles (usually ae86 corollas and S-bodied nissans) meeting up and doing donuts at crossroads, shopping centres and industrial parks, especially late at night. It`s seen by some as a starting point towards drifting where people can learn how to control a slide without serious risk of injury, but is widely sneered at by mature drivers.
People interested in diffing(differs) tend to be very young drivers who cannot afford to attend drift events and see diffing as a way of being able to be involved in the modified car scene.
Are you coming out diffing with us tonight?
We were at a (insert cruising forum name) meet last night and Dave was diffing his brothers twincam.
