Normal People playing chess VS. ME playing CHESS

You might do the same, but when I have a big advantage (like I took opponents Queen or Rook) I usually turn my leg around my chair and just SING>>>Embarrassing to type:] But, many people actually do this. My friends and I get bored after I know my opponent will lose. But, most of the time I underestimate my opponent and they get the best of me.
I know right ;)

In the beginning of the game I am hooked on focused by moves. Watching every possibility... but when I get a piece, my brain turns on dumb mode. :(

Anyway to help me stop my weird phenomenon??? Plz chat to me:@rishabhdas (I will be checking every few hours and will type back to you within 24 hours)
