When you only have one hand available cause you are driving or something and you strategically place French fries in your mouth and open the ketchup packet and squirt a bit into your mouth and eat, Hench the ketchup injection.
I was driving and couldnt squirt kechup on my fries so I resorted to the old stand by of a ketchup injection.
