Classic line by Samuel L. Jackson (that guy ALWAYS has the best lines) on the Internet Phenomenon film 'Snakes On A Plane' as Samuel's character and Kenan, from 'Kenan and Kel' try to hoist the plane left for an emergency landing after the co-pilot was killed by snakebite, whilst plummetting down to certain death.
2. Said in emergency life threatening situations where you are dependant on someone less able than you to save you from doom.
3. When you are in a car that is going to crash into another because you are moving too fast, this is the line you say just before you meet your death.
John : Shit , we're gonna die slow down, he's coming right at you Trebecc!
Trebbecc : Argh! The steering wheel came off! Shit shouldn't have joyrided with my mom's ran down car!
*The approaching lorry nears close, inch close to crashing*
John : ARGHHHH!! TURN THIS BIG MOTHERFUCKER LEFT , TROY!
Example 2 :
*Guy has to lift something heavy and take it upstairs*
*Grunts to himself* : TURN THIS BIG MOTHERFUCKER LEFT, TROY!
