What is the definition of Liverpool Blood Cells?

"Liverpool blood cells" are a peculiar bunch - think of them as the city's secret superheroes, but instead of cape and mask, they're tiny, blood-thirsty warriors with a knack for causing more headaches than a Cheshire cat's grin. They're like the city's unsung heroes, but when they decide to team up with a vengeance, you know it's a liverpool-style brawl in the bloodstream!
