She like, "damn
This the realest since 'Kumbaya'"
Bomaye, Killa Cam, my lord
The woman (actually man, but whatever..) singing in the background is saying that this is the best singalong song since “Kumbaya”, a campfire classic. The phrase “my Lord” is very prominent in the lyrics of “Kumbaya”, and Cam uses this phrase to end the line.
“Bomaye” means “kill him!” in Lingala; the term was popularized in America during the Rumble in the Jungle — the much publicized fight between Muhammad Ali and George Foreman in Kinshasa, Zaire (now Democratic Republic of the Congo) — where Ali supporters would chant “Ali Bumaye!”
Cam is using the word here as an African synonym for “Killa” (also it rhymes internally with ‘Kumbaya’)
