Ooh, hide your daughters, hide your sisters, hell hide grandmama too
Cause the fisherman's raping everybody in the pool, he on the loose, yeah

from Tyler The Creator – Fish Lyrics on Rap Genius

Meaning

The fisherman/rapist is out there, so all the fish in the “pool” (lake, ocean, etc.) should hide, and everybody in the “pool” of women should be wary of being assaulted

These lines are a play on the “Bed Intruder Song,”, and the infamous Antoine Dodson interview that led to it

Frank’s bridge also has environmental undertones, man being the fisherman, raping Mother Earth of her natural resources, like fish
