Tactical SI

~Pronounced~
Tac-tic-al -ess-eye

SI is short for 'sick'

If you are tactically sick, you are sick on purpose.

This act was common with the Romans, where they ate a meal, and then threw-up, in order to eat more food.

Nowadays this act is more common in drinking games, where someone is sick to allow more alcohol consumption.
