"Fours" is the name used to refer to a certain type of rim (hubcap), made of wire, in 1984 (where the "four" comes from). They have a fairly distinctive shape, sticking out from the wheel.

The rims are now extremely expensive and rare, having been discontinued. This type of rim is especially popular in Houston.

The term fo' fo's was popularized in the song Still Tippin by Mike Jones Feat. Slim Thug and Paul Wall. Tippin means to cruise from side to side in your car, so if you're tippin on fo' fo's, you're cruising around on your really expensive, rare wire rims.
"Still tippin on fo' fo's" (chorus from Still Tippin' by Mike Jones)

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
