Lance begins to dab after victory of every battle. Hunk begins to do it after insistence of Lance. Then it spreads and eventually the entire squad makes it a ritual to dab after every battle. The aliens that they save see this and consider it like a Voltron symbol of freedom and victory so they begin to dab. The rumors spread and it becomes a symbol of freedom against the Garla, resistance groups and aliens dabbing in protest against the Garla and in support of Voltron. The Dab Crusades.
