Lumpy Space Prince, often referred to as LSP, is the prince of Lumpy Space. He acts like a bratty, apathetic, sassy, attention-seeking and willfully ignorant teenager, often texting on his phone. He is the archetype of the teenage valley-boy "prince" affecting a self-centered, stubborn and rude persona. His off-putting personality may actually be a way for him to cope with his own insecurities about his appearance. Furthermore, he seems to be more aware than he lets on. He acknowledged the shallow nature of his friendship with his fellow Lumpy Space folk compared to the more genuine friendship with Fionna and Cake. Lumpy Space Prince can be ostensibly unmoved and uncaring about what goes on around his, using such words as "sure," "whatever," and "fine" frequently. He can also be physically apathetic and unwilling to make an effort and prefers to be the center of attention and will yell things out to regain the spotlight if ignored.
