Hello! My Japanese isn't very good but I can clarify some things. 3:48 meat (肉) is slang for penis 4:20 "boomer" (comes from "baby boomer" ベビーブーマー) is a slang for calling someone old, like in the "ok boomer" meme. I don't think it has a lot of meaning here; I think Mysta is just using it to rhyme and also make fun of himself. 5:01 hood (フード) is slang for foreskin (陰茎包皮) 5:02 Vox is saying that Mysta keeps sucking Vox's dick even though Vox is circumcised
