When a large crowd wants something so badly their primal instincts take over and they reach out there arms, push, and shove to retrieve said item.
Man, Comic-Con was crazy, those stupid collectible bags caused a zombie effect of nerds!

When a girl is giving head and wants to be warned before the guy cums to avoid any cum getting on her, the guy pulls out just before ejaculation, cums up her nose and in her eyes, creating the blindness (cum in the eyes) and the patented zombie moan (cum up the nose) and outstretched hands looking for a towel to wipe everything off with.
I gave that slut the zombie effect because she was acting like she was afraid of cum.
