Which character in The Sopranos is nicknamed 'Big Pussy'?

The Sopranos character nicknamed “Big Pussy” is Salvatore Bonpensiero, usually called Sal or Pussy. He is a longtime member of Tony Soprano's criminal organization and one of Tony's oldest friends.

Pussy is introduced as a trusted soldier and a close companion of Tony, Silvio Dante, and Paulie Gualtieri. His nickname distinguishes him from another character known as “Little Pussy” Malanga, an associate connected to Junior Soprano. The nickname is therefore not a reference to Christopher Moltisanti, Silvio, or Paulie.

Pussy's central storyline involves his cooperation with the FBI. After becoming an informant, he secretly records conversations and provides information about the Soprano family's activities. His betrayal creates intense dramatic tension because Tony cares about him personally but increasingly suspects that he is working with federal agents.

In the season-two finale, “Funhouse,” Tony's suspicions are confirmed. Tony, Silvio, and Paulie take Pussy onto a boat, confront him about his cooperation, and kill him. The storyline marks one of the series' most important early examples of loyalty colliding with survival.
