1. (verb) In the first-person shooting videogames "Halo" and "Halo 2," there is a specialized type of grenade called a Plasma Grenade. This sticks to vehicles and enemies when thrown. Killing someone by sticking a Plasma Grenade to them became known as "sticking" the other player. "Stixor," however, is an extension of "stick." It is usually used in situations like sticking someone from a great distance or when they don't notice it.
From 5 feet away: Oh, you got stuck!
From 100 feet away on top of a base into the cockpit of a manned Scorpion tank: That tank driver was STIXORED!
