👉 The term "bitchass" is a combination of words that means "a person with no dignity," and "a slut." The punchline comes from a 1985 song by the group Devo, titled "Bitch Ass". In this song, Devo's lead singer Dennis Prager sings: "Now I'm a bitchesack!"
The example sentence is from "I Am Sam" by David Koepp. In the film, Sam wants to change his name back to Sam Thompson. He decides that he should change his name to a nickname because it has been used too often and no one else would want to use it. But he thinks his new nickname might be too "bitchy."
