The word rope can be used in replace of othe conversation finishers such as later on, goodbye, safe etc.
The term was first used by one Alejandro Nunez of Crusty Treats fame, in a text message, saying:
"skeen skeen this is my new skeen rope x"
From here, the word rope was taken out of context to conclude conversations. It is hoped to become a global phenomena.
