A code word among high schoolers meaning "Marijuana".
Mostly used when
talking about such in a class full of snitches and teachers and/or campus security.
Also,
fun to see the looks on other
people's faces around you when you ask a friend if they've got "Chapstick" or yell that you need some.
Person 1: "Dude... My
lips are so dry, I haven't had any chapstick in weeks..."
Person 2: "Yeah? That sucks bro... I heard
John's got some though. We should hit him up
later for it."
Person 1: "Totally."
