Similar to a werewolf, a weregay is a man or woman who is straight during normal hours of the day, but at night turns homosexual due to intoxication or sleep deprivation. Often time this results in same sex cuddling or other homosexual actions.
"I thought Mike was straight, but last night I discovered he was a weregay when I found him cuddled with Evan, watching the Notebook."
