After-Game Kill!

Hey guys its goofyloop and I found this really cool "Glitch." I am not sure if this is technically a glitch but this is the most appropriate place to talk about. Whenever a round or match is over, the people that have died and are respawning during the end, come back to life and can shoot, not walk. So to me, after a One Man Army Junk Flea Match I died and the match was over anyways I respawned right next to another guy that the ending screen was at and I shot him with my M4 Super 90 Shotgun it made my kill go up one. Everybody was laughing really hard and it was the best kill of my life. So yeah, after respawning the glitch is that you can shoot after the match is over for a couple seconds.
