What do you consider a glitch?

I only know 2 "real" glitches

That roof in makin where you can get out of the map
and the room at castle

oh and anything that involves a bazooka/satchel is a glitch to me even though you have to do 2X health in private match to do them.

Going to any portion of a map where you aren't visible to the enemy to be shot.

Anything that happens in game that is not supposed to. Off the map, room in castle, room with bars in Cliff, too many players in 1 room, I even once had a frame delay during enemy dogs and when it finally stopped I had a 2 headed dog biting my ass.

LOL @ ^ this....

1 for each cheek.....
