Kersal Massive 

A UK 'rap' group, featuring 'C-Mack', 'Little Fuckin' Kev' and 'Ginger Joe'.

C-Mack lives by the code 'Fuck, peace!', while Little Fuckin' Kev spends his days smokin' da reefer in the corner of various forms of public transport. Buses, trains, planes; you name it, he'll be smoking a reefer in the corner of it. And what of Ginger Joe I hear you ask? He had only this to say: "Yeah man, yeah man." Wise words from a wise man. These guys don't fuck about.

C-Mack: "We know how to do it, Kersal Massive!"

Kerbal Space Program 

Kerbal Space Program is an indie space-sandbox game known for it's steep learning curve and accurate physics simulation. Many players were originally turned off by the "rocket science" aspect of the game. A phrase popularized by the game is "Add moar boosters" and it has been mentioned on xkcd.

Hey, Bob, I'm having trouble with Kerbal Space Program.
Bob: ADD MOAR BOOSTERS!

kerbal 

Describes a launch vehicle that is built by strapping together existing components, such as booster rockets or additional stages. It is a reference to the Kerbal Space Program, "create and manage your own space program", which allows players to build custom rockets in exactly that way.

"I would say that of all the new vehicles described here, the Omega is easily the most kerbal since it's just a bunch of parts strapped together." (Scott Manley, "New Glenn, OmegA and Vulcan Get Air Force Approval", YouTube, October 11, 2018, 6:38.)

the Kerbal way 

Rather than by using finesse or ingenuity, solving a complicated problem by throwing epicly massive resources to brute force a solution.

Elon Musk: "At first, I was thinking we would just scale up Falcon Heavy, but it looks like it probably makes more sense just to have a single monster boost stage."
Skov: "Nice to see you are doing things the Kerbal way."
Elon Musk: "Kerbal is awesome!"
