A splum is the metal grommet or fabric eyelets that are often sewn or attached near the top of each of the six sections of fabric of a baseball cap to provide ventilation.
The splum of my baseball cap feels like it dented my brain when I hit my head on the low ceiling.

Splum is penguin meat (usually emperor penguin meat) served with pineapple, it is owned by Glutwell, a major compony. Glutwell has established a restaurant for splum in the arctic (making it the only resteraunt in the arctic circle) most like put there as a food sourse for the people who work at the secret military base(also owned by Glutwell) and also the natives, this makes sence because they can just harvest the emporer penguin meat there. And before someone says that penguins only live below the equator well Glutwell probably put the penguins there.
The scientists stoped to get some splum after their hard work at the military base
