To intimidate, bully, or push someone around; to use aggressive tactics to get what you want.
Derived from Humphrey Bogart, the famous actor known for playing tough, intimidating characters in film noir movies. The verb emerged in American slang in the mid-20th century as a reference to his on-screen persona.
