I'll have to go with the neoclassical "shit" and "fuck". Fuck is just so throwable, and can be inserted easily into any sentence, while also working as a standalone. Shit works wonderfully well as an adjective, and is equally throwable.
"Man, fuck this shitty lab TA. She hasn't given us back any of our fucking lab reports yet, and that shit's graded."
^True story.
