If I say zap, you’d still be right because ‘retweet or zap’ still holds. If I say ‘retweet the question’ then ‘retweet or zap’ is still a valid thing to ask as above. So the only way you’d be wrong is if ‘Retweet or zap?’ was an invalid question?

Invalidated by either option not being possible?

Ugh I don’t know how to do it.
