A small glass container filled most often with coke, however it can contain other drugs such as K (ketamine). Apple Tops of coke cost 10 bucks, a dime. The name apple top comes from the small circular black cap on the small glass bottle that has an apple print on it. Possibly the trade mark of the comapany that produces these small glass bottles.
"We stay slangin apple tops up in the Bricks, 10 for 70 boi. Shits raw."
