is saying "EZ" toxic?

just came off a game where I said EZ after a boss ass play. problem is, I think an enemy got tilted because I said it (were ranting in all chat). I then remembered the times people said that to me and I died a little on the inside, and now I immediately regret my life choices >_< but is it actually OK for me to say EZ or something along the lines of it, or should I generally not?
