auxiliarator
A separate and highly-effective-but-street-illegal nitrous-oxide valve dat really puts some ZIP in yer car's performance.
If you use an AUXILIARATOR in conjunction with your ACCELERATOR, you may indeed experience EXHILARATION from your vehicle's awesome ACCELERATION, but you will also stand an ACCELERATED chance of getting pulled over for speeding and/or reckless driving! Best to instead reserve said speed-demon shenanigans for da drag-strip!
