"Foune scentencek."
"Fonue scentkence."
"Fone uscenktence."
"Fone suentecncke."

Nope. Can't do it.
Zero it is.

I was always fond of: "Fuck you, you fucking fuck."

I don't really give a flying fuck about the answer, but does fucker count you fucking motherfucker, because if it doesn't I'm fucked, but if it does then I think I can craft a fucking sentence filled with fucks that'll last longer than me when I'm fucking my smoking hot wife.

If you follow "Buffalo" rules then

Fucks fucks fuck fuck fucks fucks fuck.

is a perfectly valid sentence.

For fucks sake, you can say fuck as many fucking times as you fucking want; with fucking commas and those wiggly fucks semicolons, one fuckton of fucking fucks can be fucked into the hole of a sentence.

You might enjoy Limp Bizkit

A fuck load

None, apparently.

Fucking okay, look you fuck.

I'm the fucking OG, so fuck your fucking oatly and gimme the real fucking oats I fucking crave the ones that'll make my fucking life fucking saved, and fucking mix them fuckers up with butter and shit until the fucking thing is totally fit to fucking burst and fuck up my insides, so take me for a fucking ride and bite my fucking cookie, son, we're fucking on.

That's fucked. Now I gotta go rewatch all those fucks in "Casino" to fucking train, you fucking fuck.
