Isn't it how you say, "stfu" irl..?

Maybe it's just me who says internet acronyms out loud.

Or it could be his real name is Stiff or similar in phonetics so he went with that

Haha, teh_saccade had the correct hunch! I got this nickname from my friends while playing Mario Party back in school! I cracked a highscore and everyone was shouting "stfu" because they couldn't believe it! :-D
