Name ideas for for a league couple.

Hey guys, my girlfriend and I are looking to change our names to somewhat matching names. Names could be antonyms of one another, have innuendos, or just all-round game/comic/movie references, etc. She and I are both pretty big nerds so most references would be understood so shoot for it, just as long as they're aligned with one another. Help would be much appreciated. Person with best suggestion gets a mystery skin from myself, just don't forget to add your summoner name with your suggestion.
