Xenomorph

Featured in Alien, Aliens, Alien 3, Alien Resurrection, Alien Versus Predator, and the upcoming Alien Versus Predator: Requiem, a Xenomorph is a particularily nasty creature.

First, a queen lays an egg, which opens and releases a Facehugger, that proceeds to latch on to someones face, and implant an embryo into their throat. The embryo grows until it no longer fits, and then eats and smashes through the chest of the victim, most likely, killing it. The newborn Chestburster must feed to grow into an Adult.

"A Xenomorph may be involved," ~Lieutenant Gorman
"It's a but hunt," ~Corporal Hicks.

Xenaholic

Somebody who is completely addicted to Xena: Warrior Princess. There are different ranges of Xenaholics. Anybody who watches a couple episodes of Xena a day on DVD would be a mild Xenaholic. However, people who own all 6 seasons on DVD, spend the majority of their time watching and/or worshipping Xena, have Xena posters on their walls, walk around quoting Xena, and even comparing themselves to either Xena or Gabrielle, would be considered heavy Xenaholics. Some Xenaholics may also have interest in Hercules, and probably have a few seasons of that on DVD as well.

My mom and I are both proud Xenaholics. We watch it every day.
