What does "bogambo" mean when Kramer says to George "Hey Bogambo they've been in the neighborhood for 48 years"?

Question

What does "bogambo" mean when Kramer says to George "Hey Bogambo they've been in the neighborhood for 48 years" in the Seinfeld episode "The Mom and Pop Store"? What is the reference here? The only thing I could find on Google is a similar word "mogambo", but I don't see why that would be funny or make sense.

Answer 1

Reviewing the script:

Hey, Bucambo...

they've been in the neighborhood for 48 years.

Googling for "Bucambo" it might be considered to be a running gag that Kramer uses nonsense nicknames for people:

Kramer uses strange nicknames for George, such as 'mojambo', which he comes up with on the spot.
