D.S.M.F.S. 

an acronym meaning: Damn Straight Mother Fucker Shit.

Originally used by Jan Johnson while he coached pole vaulting. He uses it to compliment a good vault. It is versatile, however, and may be used after any achievement (no matter how small).

Pronunciation is just saying the letters with a successful tone.

"DUDE! I just ran 5 miles in 1 minute! D.S.M.F.S.!"
