Can a defender evoke offside by...?

Question

Can a defender (yes, this is the last defender before keeper) step out of bounds to evoke an offside call on an attacker (not yet in possession of ball)?

Can you please give me line and verse in the Laws of the Game that supports your answer?

I know technically what offside is... now I want to know what happens if that last defender before keeper steps out of bounds.

(and I don't mean to sound gruff, but without line and verse, this just turns into another "opinions are like you-know-whats" debate at a pub)

Thanks !

Answer 1

I cant give you an line from the rules that says if it is an actual rule

But i have seen it work in pro games and not work in pro games
