D.S.M.F.S.
A loud shout of praise for someone who just did something awesome. It means you're so impressed you might throw up. Used by Jan Johnson when someone vaults higher than a giraffe.
D. S. M. F. S.! You just jumped over a flaming pizza!
D. S. M. F. S.! That vault was so good I cried.
D. S. M. F. S.! You just made my day. I might have peed my pants.
