• a filmcanister

I came across this word while reading “how to date a brown girl” by Junot Diaz. This word was found on the second page, it quoted “A local girl won’t need stories about the neighborhood but the other ones might. Supply the story about the loco who’d been storing canisters of tear gas in his basement for years, how one day the canisters cracked and the whole neighborhood got a dose of the military-strength stuff” I understand that the narrator is talking about tear gas being stored in the basement.
