These crocodile attacks became the source of local legend and mythology, named Bujang Senang (happy bachelor) which refers to a 19 ft-crocodile that inhabited the Lupar River. The colloquial name of "bujang" means someone who is a champ, a great person, and it is a sign of respect while “Senang” refers to the Senang River, one of the tributaries of the Lupar River where the first known attack by this crocodile had happened. In popular culture, the name Bujang Senang (the Crocs) was adopted as the nickname of the state’s football team Sarawak FA.
