Something you silently mouth to someone to return an "I love you". When you silently mouth "olive
juice", it looks
like "I love you". A silent "olive
juice" is usually used when someone tells you they love you, and you want to keep them, but you're not ready for that.
Man, Christie told me she loved me last
night. I don't really wanna take that step yet, but I don't want her to dump me. . .so when i saw that she was waiting for me to say it back, I just mouthed "
olive juice" and started making out with her.
