What does GOAT or 'GOATing' mean?

I've heard this a few times in Guild Wars 2, usually in the context of a PvP or WvW match.

Someone will be complaining that

There was too much goating in that match

or

That guy is a professional goat

What does it mean?

Solution 1:

It's something I rarely hear, but associated with multiplayer online games (especially PvP in with objectives) it usually means scapegoating.

Now I haven't played a lot of GW2 but in WoW PvP or LoL matches you sometimes accuse someone of goating if he blames another teammate or his internet connection.

For the term "He's a professional goat"... well I've never heard that to be honest but I think it's someone who always blames others.

Solution 2:

One suggestion I got from someone in-game was Greatest Of All Time

Indicating a player who was playing really well.

So

There was too much goating in that match

could mean there were several players in a PvP match that were untouchable.

I just can't remember what context I heard it in.
