Poetry/Word Cypher.

Here is the Urban Dictionary definition of a cypher:

“A cyclical artistic action for several artists. To freestyle but not in battle terms. If you’re freestyling, you rap in a cypher (one after the other). Interrupting another man/woman will break that cypher (unless she/he’s next in line and the dude behind her/him is falling off). The same concept applies to burning; there is a set order to who hits next (pass it to the left my friends). Never break the damn cipher!”
