Let me off, screeching halt
Concussion blinding
Not my fault
Ankles tied to cinder blocks

Meaning

Everything is coming an close extremely fast and unforgiving. Finds himself suffering from a concussion with his ankles tied to cinder blocks. Game over.

Due to the way in which he announces “concussion blinding”, it sounds as if he’s saying “gushing blood”. This is most likely deliberate, adding to the imagery he’s illustrating.
