“don’t try to sing this
some drop science; while i’m droppin english”
- That’s from NWA (Dr. Dre, specifically) 1988. This particular line leads me to believe that someone had “dropped science” prior to 1988. A good lead to go on would probably be KRS-ONE/BDP. It’s interesting to note that, in 1988, both KRS-ONE and NWA used the line “it’s not about a salary it’s all about reality,” so maybe there was a little bi-coastal lyric sharing going on there.
On second thought, I may be way off here, I just checked the rap dictionary and it has this to say:
So I guess, unless you find a usage prior to 1988, this is what you were looking for.
