The moment just prior to having uncontrollable diarrhoea. A red light gives you approximately 10 seconds to make it to the bathroom before wherever you are becomes ground zero for a "pooclear" explosion.
I was on the train to work this morning when without warning I got a red light and some fucker was in the bathroom! I had no choice but to go in the sink!
A game played by two people where player 1 puts their hand up player 2's pants, if player 2 gets uncomfortable they say "red light," this means player 1 wins. If player 1 gets uncomfortable and takes their hand out of player 2's pants, player 2 wins. If player 1 touches player 2's genitals, it is considered a draw.
Player 1: Want to play 'Red Light'
Player 2: sure!
(Player 1 slowly moves their hand up player 2's pants until they are just about to touch their scrotum)
Player 2: RED LIGHT!!!
(Even though player 1 has won they continue and end up giving player 2 a handjob)
A way of telling someone to be quiet, or shut up. Or it can be used a way to interrupt.
*Girl Talking Shit*

Girl 2 - I'm going to have to red light you real quick. Stop talking shit.
OR.
*Two males in fight*
Guy - Is it a scrap? Like what's good? Nize it.
Guy 2 - Nize it? RED LIGHT, RED LIGHT. Come at me then.
