Is playing instant action card buh bye on defense priority over an Offenive ability
Quick answer
The rulebook doesn't name a card called "Buh Bye," but by the general rule, Instant Action cards can be played at any time, including to interrupt an Offensive Ability.
Details
An Instant Action card is defined as a card that "may be played at any time during any player's turn" and can interrupt normal play [p.9 — QUICK REPRIMING]. This means it can be played in response to an Offensive Ability being activated, effectively giving it priority to resolve before the Attack completes.
However, there is an important limitation: Instant Action cards (and Roll Phase Action cards) cannot interrupt Spendable Status Effects or another Instant Action / Roll Phase Action card [p.9 — QUICK REPRIMING]. So while an Instant Action card generally has priority over an Offensive Ability's resolution, it cannot "jump ahead" of another Instant Action card or a Spendable Status Effect that's already being resolved.
Watch out: The rulebook excerpt provided does not include the specific text or effect of a card named "Buh Bye," so its exact interaction with a particular Offensive Ability (e.g., whether it can stop an Ultimate Ability, which explicitly cannot be interrupted except by altering a die roll [p.9 — QUICK REPRIMING]) cannot be confirmed here. Check that card's specific wording for any Unique Status Effect or exception rules it may carry.
