"Guba", noun, is the name of the gear, or outfit, you are wearing when you combine full SCUBA gear with
Hockey Goalie gear. This outfit is commonly donned in the wake of an armageddon, while preparing for an Armageddon, while preparing for an
apocalypse, upon receiving news of an oncoming
apocalypse, or in worst cases, just as the apocalypse hits. This outfit is also known to be popular during non-apocalyptic times in various doomsday-prepper cliques, often considered a showing of prepping prowess by donning the uniform randomly and unexpectedly for no given reason.
