In Thomas Pynchon's "The Crying of Lot 49," the phrase "keep it bouncing" serves as a metaphor for sustaining momentum in life and interactions. The concept implies that maintaining energy and engagement is vital, whether in personal endeavors or social connections. This idea reflects the chaotic and unpredictable nature of the modern world, where connections and meanings often shift unexpectedly.

The character's advice suggests that rather than allowing experiences to stagnate or become dull, one should embrace change and movement. This resonates with the overarching themes of the novel, which explore communication, disconnection, and the search for meaning in an increasingly complex society. "Keep it bouncing" embodies a proactive approach to navigating life's uncertainties.
