I was playing on wormnet and one guy killed a worm of mine using a girder. He just placed it on the worm and it popped out of the scene dying. Half of the girder was on the land and the other half in the air. Is this possible? If yes how do i perform this kind of "attack"?

This is a known bug.
People who exploit it are idiots. Remember their names and don't play with them again.

BTW, this bug and many other exploits have been fixed in WA.
You might consider switching.
