Infra-red all inside your bumbo, rasta

from Raekwon (Ft. Cappadonna & Ghostface Killah) – Ice Water Lyrics on Rap Genius

Meaning

Pun on red here. “Bumbo” is jamaican for ‘cunt'
Bumbo means backside. He’s saying his gun is aimed at your ass (probably not literally — that would be weird). Just some JA slang to fit with the rasta reference.
