Mundus and Lilith do it all the time:troll:
I don't think that Lucifer scene was as terrible as some youtube comments have made out. Sure, it was a little unexpected, but it could have been worse....much worse. It's just Dante goofing around. It's not like he's actually humping the hell portal while he's destroying it.
That and its a reference to the weapon itself has a lot of weapons (well ALL of the weapon's) moves are named after BSMD terms or sexual references such as Pin Up, Ectasy, Bondage, and Climax.
Unlike "DONKEY PUNCH!" it has a significant relevance to Dante's actions when he did what he did when he used Lucifer in that cutscene.
