A "shield" armor in Halo or Halo 2 that is 3x as damage resistant as normal.
"Wow look at that deusch of a guy wearing that overshield because he is scared shitless someone is going to kill him in a video game!"

"Don't you snag my overshield or ill have to poop all over your chest"

Get the Overshield mug.
Referring to the game halo or halo 2, an overshield whore can be used to describe a team or just one person that takes the item overshield everytime it respawns.
That team is so damn cheap, they only won because they were being overshield whores.
