In Jodi Picoult's book "Between the Lines," the author explores themes of masculinity and the different ways men express confidence and identity. The quote, "Men don't traipse. We... Swagger," suggests that men often exhibit a more assertive and bold demeanor, which is characterized by the swaggering gait rather than a casual stroll. This distinction emphasizes social expectations surrounding male behavior and the pressure to portray strength.

Through her narrative, Picoult delves into the complexities of male characterizations, illustrating how society shapes perceptions of masculinity. The notion of swagger implies not only physical presence but also a deeper narrative around power dynamics and self-perception, prompting readers to reflect on how these traits are portrayed and internalized in various contexts.
