The name Billlie is spelled with three Ls due to the fact that the name can be broken down into 'Bi' (Korean word for rain), '11', and 'lie' — Bi11lie. The number '11' came from their group's legend; "When the 11th bell rings in the middle of a purple rain, something strange happens", where the members lie about what happened in order to keep the event a secret. The name also reflects their "B-sides, the inner-self that everyone has inside them", which they express in hope to empathize with the audience.
