In Nick Joaquin's story "Cándido's Apocalypse", Pete Henson tells Bobby, the story's main character, that
"Joey Perez and some fellows went joyriding and dog-hunting and they caught a good one. They're going to roast it in the vacant lot behind the Gatdulas and they have a fine collection of longnecks and cuatro cantos. The barkada's there. (...)"
Pete and Bobby are members of a band named The Vultures. Barkada (from Spanish barcada) is Tagalog for gang or clique.
Canto is Spanish for "song" but from the context it is doubtful that Pete is talking about songs here. I assume "cuatro cantos" (literally "four songs") is slang for something else here, but I have not been able to figure out what it means.
Update: longneck can mean "a type of beer bottle with a long neck", so "cuatro cantos" is most likely related to alcoholic beverages.
