A bit grammatically incorrect … i got it when camping on top of the axis tower in the first phase and it got dynaed… i fell a bit then i got gibbed and it said i was killed to death lol.
Fueldump "[name] was killed to death"
shouldn’t you write “… i was killed to death, lol”? i mean with a comma or a period. and dynaed is not a word 
who cares? 
He means he was “pushed” by the explosion of the fueldump blowing up.
So infact he was killed to death by the fueldump.
doesn’t happen everyday…but to make a post out of it? =P
Unless you got it on demo ^^

You always get killed to death if you are near the fueldump when it explodes.
The same happens if you are in an MG tower (Fueldump map) and it gets destroyed.
As far as I remember.
its just the games way of explaining deaths without a set description (if i rember right) like in halo when you are “killed by the spirits”
Just had a quick look at the map.
I’ve thought that there are trigger_hurt brushes around the dump.
But nothing.
So maybe I’m totally wrong.
That seems correct. (I just tested it in the first MG tower as well, same thing there.)
edit
Doesn’t seem to happen in etmain (only etpro), which explains why I can’t find it in CG_Obituary.
