In the gay community, it's an adjective used to describe a sexy guy, but not the feminine kind of guy, but a more masculine guy; one who you wouldn't identify as being gay if you saw him on the street.
Coined by Dr.PerryCox from the medical comedy show Scrubs, it is now used as an overall exclamatory remark towards anything deemed angering, sexy, cool etc.
