1. A sudden uncontrollable climactic response while listening to music - often characterized by the exclamation of 'Weee' or 'Oh yeah' while listening. It is followed by a refractionary period of disinterest.
2. A musical orgasm, not necessarily dirty.
I love OK Computer (Radiohead). I can never make it through the whole album; I always have a morgasm before Electioneering.
Any orgasm with wither morgan freeman, or morgan (last name removed) involved. Only few have survived. Others described intense pleasure followed by insane hallucinations. If the 2 morgans get together, the world will end. We must keep them seperate.
Oh my god. You're flashing colors again. Have you been messing around with morgan? Morgasms can kill you, you know.
