Lightspeed Systems 

A crappy web filter used by schools to block everything good on the internet. The filter blocks games, blogs, youtube, etc. It is a highly restrictive filter designed to surpress free speech and expression.
Person 1: Lets go on Urban Dictionary!
Person 2: We can't. It's blocked by Lightspeed Systems.

Lightspeed Champion 

Amazing music.

Also a character in comics drawn in maths books.

Lightspeed Dickslam 

The act of slamming one's genitals at speeds in excess of 45 MPH. One person must drive down a highway, or any road that has the correct speed limit. They must drive on the far right or the far left lane of the road.

Person #2 must be on the far left or far right of the car, putting themselves right next to the shoulder of the road. They must then pull out their genitals and stick their dick out of the window.

Person #3 does not have to be a willing participant. They must only be a bystander on the shoulder of the highway.

If all 3 people are present and doing their jobs, then Person #1 will accelerate above 45 MPH whilst going past Person #3, who will be slammed with Person #2's dick and what would feel like lightspeed.

Note: Person #2's dick must be longer that the side mirrors of the car, or else it becomes a Lightspeed Side-mirror-slam. For this reason, black men are ideal for Person #2, and Asian men are highly discouraged.
I heard that Joe got Lightspeed Dickslammed the other day while walking home from the mall.

Serves him right. Why was he walking from the mall?

Word of the Day on October 4, 2026
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.
