Kill Frenzy Medal
From Halopedia, the Halo wiki
The Kill Frenzy Medal is awarded for killing 10 opponents without dying in the act. It is available in all Multiplayer gametypes, and has a Bungie difficulty rating of 8 out of 10. It is represented by a silver medal with 5 stars. When someone gets this medal the announcer will shout "Kill Frenzy!" to the player that received this medal. In Halo 3, this is know as Killtacular.
