Someone who is having temporary memory shut down, often occurs after a night of drinking or gettin stoned, staring into space often occurs when diagnosed with empty headedness!

One who chooses to wear a mask.

Term for someone who is open-minded enough to adopt an untenable theory (often some kind of crackpot conspiracy), yet close-minded enough to reject all criticism of that theory. The combination of echoing empty space and solid, impenetrable plastic makes rational communication impossible.

A person of poor character, work ethic, and limited intellect. Popular in the Niagara Region of the province of Ontario, Canada beginning in the late 1990s. The term may well have migrated from Alberta.

when you have encountered so flabbergasting that your brain cells have left the chat, leaving you with no thoughts, speechless.
