Tank Girl: The Rippers are a demonic army of bloodthirsty, human-eating, purse-snatchin', mutant creatures.
Art Shift: The movie is interspersed with images drawn in the comic book style, as well as a few somewhat related animated sequences. This was pulled whenever they didn't have the money to shoot the scene they wanted (especially the ending) so they animated it instead.
"Listen up, cause I'm only telling you this once. I'm not bedtime story lady, so pay attention. It's 2033. The world is *screwed* now. You see, a while ago this humongous comet came crashing into the earth. Bam, total devastation. End of the world as we know it. No celebrities, no cable TV, no water. It hasn't rained in 11 years. Now 20 people gotta squeeze inside the same bathtub - so it ain't all bad."
Bad Boss: Kesslee, Up to Eleven. He kills a loyal minion/doctor because she couldn't repair his face. So, downloading him into a holographic projection of his head is somehow an IMPROVEMENT?!
He also kills a competent captain of his men, because he hadn't yet captured a small area of land. Maybe if he didn't kill the all the competent people, he would have survived.
Boyfriend Bluff: Tank Girl pretends that Jet Girl is her girlfriend to get Sgt. Small to leave Jet Girl alone.
Bring It: Kesslee's gesture to Tank Girl's tank just before it starts firing at him.
Death World: Let's see, an evil Mega Corp. with its own Mildly MilitaryElite Mooks hunting and killing whoever they can find, almost no water, monster killer kangaroos... check, check and check. Granted, it's pretty heavily parodied and subverted by the end.
Hypercompetent Sidekick: Tank Girl is fairly competent on her own, but her sidekick Jet Girl is significantly saner and somewhat more practical, meaning that because of her most of Tank Girl's schemes don't end with her dead.
Idiot Ball: Tank Girl deciding to stop for a musical number in Liquid Silver instead of escaping, which leads to Sam being captured.
Wild Take: The animated Jet Girl's reaction upon seeing the animated Tank Girl pointing a tank's cannon at her before firing.
World of Hamand Cheese: Lori Petty is a freedom fighter who drives a tank with "Tank" and "Knat" license plates, a cyborg brain, a charcoal grill and loads its cannon with beer cans when she runs out of ammo. Ice-T proudly plays a mutant kangaroo. But most of all, Malcolm McDowell plays Kesslee, the director of Water and Power. He knows he's just there to make fun of the whole crazy mess of a movie. WATER! IS! POWER!
