The shit you take before you go out at night. Failure to take one can result in holding back a fart or even a shit in front of girls or others. Taking a preemptive allows for maximum beer drinkage and room for a late night meal.
Johnny: "Yo dude when these girls leave I'm gonna rip a sick fart."
Bobby: "Dude you defintely didn't taje a preemptive shit. We're going to the diner in a little bite."
Johnny: "Fuck!"
