STP
A street name for the drug DOM, a form of petroleum waste. Dom was slightly popular in the mid-60s, being a masivly powerful hallucenagenic, much stronger than LSD, however popularity dropped off after a large number of overdoses and deaths, due to the fact that hospitals did not know what "STP", the most common name, was, the patient would suffer severe brain damage or death, sadly overdosing on Dom is a fairly cureable situation if done so timely, but it took too long for hospital staffs to make the connection of dom to STP.
man my uncle took some STP when he was younger, he fucking fried his brain with that shit!!

STP
An old adage from the 1960s to the 1980s, during the Indianapolis 500 glory days of the partyin' Snake Pit in Turns 1 and 4, meaning to "Start The Party." Of course, this was before the evil Tony George took over the Indianapolis Motor Speedway and made it family-friendly.
