The Doom Generation (1995)

This campy romp through the idealized world of mid 90s anarchists follows Jordan White and Amy Blue, a high school couple addicted to marijuana and meth, who serendipitously join forces with wild man Xavier Red in an emergency situation in which they blow a convenience store owner's head off. From there the trio flees from cops, gangs, and psychos all the while partaking in every disgusting sexual act you could think of, culminating in the final scene which makes me want to vomit just thinking of it so I'll spare you the details. There may be more to this film than a list of 100 violent and sexual acts dipped in a heavy coat of the 90s counterculture scene, but you've got to look for it. Maybe it's in the outrageously cheesy special effects and blood scenes or maybe it's in the exposure to the extremely exaggerated world of degenerate punks. Either way, if cheap campy movies appeal to your dark side then, like a car wreck, you won't be able to look away from the uninhibited sexual exploration and extreme violence.
