So, next time that you think you want somethin here
Make something def or take that garbage to St. Elsewhere
Phife is saying that if you want to be on par with A Tribe Called Quest you better be really good, or else go to St. Elsewhere (a TV show; here, used in reference to slang that refers to lesser-equipped hospitals that serve people who are not wanted in more prestigious institutions).
This basically is telling rappers that they better spit tighter lines, because ATCQ doesn’t want them and their stuff should be featured in less famous and prestigious albums, groups, etc.
