Bell-Ringer 

A hit of crack cocaine that is particularly strong. Commonly regarded as the 'holy grail' of rock smoking. This often results in a ringing of the ears, hence the term.

The intense feelings of euphoria, well-being, godliness, and ultimate satisfaction are often accompanied by nausea, vomiting, sudden bowel movements, hallucinations, and paranoia.

Fun Fact: A hit that leaves one with poo in their pants is highly esteemed in some crack circles.

"I am going to load up a shitload for this next blast. I need a fuckin' bell-ringer son!"

"After I have smoked for a few days I find it impossible to achieve a bell-ringer."

"Don't run your mouth while I am in the middle of a god damn bell-ringer, god damnit."
