D.S.M.F.S.
A shout of happiness when someone does something so good it makes you want to punch the air. Jan Johnson screams it when a kid vaults like they're on fire.
D. S. M. F. S.! That vault was so good, I want to punch the sky!
D. S. M. F. S.! You just jumped over a flaming unicorn. I love it.
D. S. M. F. S.! I think I just got a new high from that vault.
