The term "LABAN" is an abbreviation of Lakas ng Bayan ("People's Power"), a former political coalition organised by opposition Senator Benigno S. Aquino Jr. for the 1978 Interim Batasang Pambansa regional elections.

In 2021, upon announcing the presidential bid of Vice President Leni Robredo for the upcoming 2022 elections, the gesture was associated with her campaign.
