Cheering on a loser

You know how in football and other games they cheer on a winner. Well I have an "opposite" idea of cheering on a loser: when someone loses you just yell "loser! loser! loser! loser! Forfeit! Forfeit! Forfeit! Forfeit!" and yes, I also want to "cheer on" my chess partner when they are losing. I guess what stops me from doing it in that exact way is that the word "forfeit" almost sounds like I am asking them to resign. But I don't want them to resign, since I want to prolong the pleasure of winning the game. But still I want to use the word "forfeit": yes I learned that word from chessclub.com (otherwise I am native Russian speaker so I didn't know that word even existed) and there is something about that word that I enjoy in a sadistic way. So yeah I really want to cheer on my losing partner with that word without having them actually resign. Can anyone else relate to it? 

Nope!
