Slackness has been a part of Jamaican music from the very beginning. Many tunes are quite offensive like Busters "Rough Rider", but there are as well many tunes where the lyrics are suggestive or ambiguous.
Since i'm no native speaker some tunes have passed my ears without realizing their slack content. But i'm curious which are..
Ok, i'll start..
1. Jackie Opel - Push Wood
A quite obvious one with Jackie talking about his nymphomaniac woman (I want mash again!)
2. Lloyd and Devon - Red Bum Ball
Never thought about it, but over at Dancecrasher a user called Jumbo statet "[..]it’s about about a memory of teenage sex in school, he refers to her Red BUMBO and how she cried when he ‘took it away’." Makes sense to me..
