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 Ares I is the most kerbal rocket ever made. It is essentially a crew capsule on top of a Solid Rocket Booster.

Kerbal 

Adjective used for describing engineering projects (specifically rockets, aircraft, or spacecraft) that are massively over-engineered, have a remote chance of working as intended, or are otherwise absurd. From the game Kerbal Space Program, a popular spaceflight simulator where the player controls the space program of the titular Kerbals, a race of little green men who, in the words of one developer, "only do the wrong thing all the time, and have stumbled into being an interstellar civilization."

The Sea Dragon was so kerbal!
