It is a fallacy of equivocation between the operations ...
Logical disjunction is an operation on two logical values, typically the values of two propositions, that produces a value of true if at least one of its operands is true. The truth table for p OR q (also written as p ∨ q, Apq, p || q, or p + q) is as follows:
