A liquid that will freeze your fucking asshole off even colder than fucking liquid nitrogen or Dry ice I dare you to drink it.

Man 2: Nah dude gasoline is better
Man 3: Liquid nitrogen is way better
Man 4: liquid helium is the coldest you dumfuk
Man 3: no its not
Man 5: well I'll try lava
(everyone drinks their favorite suicidal drink)

eyes like Liquid helium
