Can this get you banned?

So the link above is a short YouTube clip with a trolling flute/recorder playing that says GG Easy Noobs. I sometimes say this after games in the chat lobby where you can see stats etc and I usually get responded back by other players reporting me because I was trying to be funny. I constantly get Warnings that say every one has off days etc... I generally only type in the league chat if I want to notify my team and things I cant use ping for and I don't rage or show any feedback that I am angry at my game so honestly pretty much can I get banned by just showing the YouTube clip above after games to show I won.
