What is the definition of Totally Blood Cells?

"Totally blood cells? Like, seriously, these are the little warriors of our circulatory system who keep our brain on track while dodging traffic jams in the veins! They're the unsung heroes of our daily commute, but they secretly have a taste for spicy food because, you know, blood is like the perfect condiment for a crisis."
