Buzz, so to speak

CALL

Think of what you might do with a phone to get someone’s attention—it’s not a text or an email.

Buzz" here isn’t about the sound a bee makes—it’s slang for a phone call, like when someone says "give me a buzz" to mean "call me." The phrase "so to speak" hints that the word is being used in a non-literal way, pointing to this common informal meaning. So the answer is "CALL," since that’s what you’d actually do to create a "buzz" in this context.
