I'm not sure if you meant baking or biking but if you meant biking then it basically means it's unsafe and one you get in an accident your brain would uh fall out so yea.
Predicate pronoun
A predicate pronoun is any pronoun that is part of the predicate.
A predicate is the part of a sentence that includes the verb and the words following it that relate to that verb.
Examples:
I will call him .
The teacher gave us a history assignment.
Mother made lunch for them .
A sentence may have more than one predicate; for example:
Mother made lunch for them and set it on the picnic table.
A subjective pronoun can be part of a predicate when it is the subject of a clause,; for example:
Mary brought a cake she made for the party .
A subjective pronoun is also used as a subject complement when it follows a linking verb; for example:
The leaders right now are he and I .
