Either to nuke or deny means that either you can kill yourself with a single strike on purpose, since the Ability Details state that he can kill himself, and to deny is a mechanic that currently doesn't exist in the game, to eliminate an ally unit or the user him/herself in order to deny gold and experience to the opponent, in order to be healthy would need to be applied to every single champion in the game, else is toxic.

Also Gangplank's Q used to deny minions.
