Among gay men, something that is extremely gay but also generally enjoyable. Used in a generally positive, if somewhat arch or ironic, way.
There were drag queens and go-go boys and porn stars at that party in the Hollywood Hills, and I was up all night partying with those guys. Totally over-the-top and fagalicious.
1.Someone so abruptly gay that they seep rainbows from the very homoerotic pores of their silk loving bodies. Commonly only found in the colon-like depths of Castro Street, San Francisco.
2. Some one so deliciously gay they are only equal to that of elton john and butt plugs
Adjective: When a gay male is having an extremely fantastic day and feels like the world is made for him. A perfect day when everything is going right. When a gay guy has a day full of seredipity. A mental high. A combination of the slag word "fag" used between gays, and delicious = FAGALICIOUS
Gay Guy #1: Hi, Brett, how are you doing today?
Gay Guy #2: I feel fagalicious today, Ronnie!
