A term often used to refer to, possibly, the most extroverted gay man you could know. It is preferred not as an insult, rather a more factual
description, where any doubt is quickly put to rest.
Some say it originates from co-host Adam on the
Nobody Likes Onions podcast, but this is not irrefutable. Other sources suggest it has come from a concept of the original gay, where Adam (as in Adam & Eve) represents the first human male that committed the
original sin. Admittedly it's a slightly tenuous spin on the idea of Adam being the original.
