I'd like to see Respect the onions as a new official one. Also since Rick-Rolling got kinda lame I'd like to see people get Fridayed(you know what I meanXD) instead.
In Metroid Prime 3, attacking fellow crew members on the GFS Olympus results in the Computer drawing Halberd-Class Defense Turrets, telling u to knock it off. Continue shooting and the guns will skin your hide, destroy them and stronger turrets will replace them, destroy those and an indestructible will brand a death straal, ray at you, which cannot be dodged.
