A "guyzer" is likely a misspelling of "geyser," which refers to a natural hot spring that intermittently ejects a column of hot water and steam into the air. Geysers occur when underground water is heated by geothermal energy, creating pressure that eventually causes the water to erupt. Famous examples include Old Faithful in Yellowstone National Park. If "guyzer" refers to something else, please provide more context for clarification.
