Too many rough motherfuckers, I got my suspicions
That you're just fish in a pool of sharks nigga, listen
from Jay-Z – 22 Two's Lyrics 2 on Rap Genius
Meaning
A lot of rappers pretend to be rough, but they are really fish masquerading as sharks

Jay-Z expresses a similar sentiment in “Change Clothes”:
Y'all niggas acting way too tough
Go get a suit, get it tapered up
Too/two count — 3
