Nangs or Nangers, plural.
Nangerator, a device used for cracking nangs.
A nang is the Australian slang term for a co2 (nitrous oxide, laughing gas) canister, intended for whipping cream but also used as a recreational drug.
They're also known as bulbs, whippits (reference to whipping cream) or cream chargers.
The nang is "cracked" with a nangerator; a soda syphon, commercial cream whipper or purpose built unit made to depressurize the gas for inhalation. The name comes from an auditory hallucination some users get while effected. A heavy user may be dubbed a "nangasaurus rex"
"Hey El chuck us another nang"
"......Ummmm, there aren't any left"
"goddamn it Elena, you are a friggin' nangasaurus"
