It's short for (R)ussian (D)eath (B)utton. It is specifically referring to Tulums and CRVs (Medium and Light 500m rockets that do very good Splash damage.)  I don't know why it is considered Russian lol. The Ork/Pinata loadout (300m Medium and Light rockets) is just the (D)eath (B)utton. Both Death Button loadouts are almost always referring to either a Rhino or a Griffin, as they both have 2 Medium and 2 Light weapon hardpoints, and that much splash damage in a single salvo, if used well, can be enough to kill most bots of a similar level. Since you hit the big red button once to fire them, and it causes the death of most bots... the name is apt. :)
