How to have a bad orgasm

Last night I learned the hard way how to have a bad orgasm.

That sounds wrong...

Anyway, I wanted to make myself an orgasm, which has Bailey's and Cointreau in it, plus some third ingredient I couldn't remember.  So, I looked it up.  The IBA recipe I found called for Bailey's, Cointreau, and Grand Marnier.  That seemed like a lot of orange flavor to me so I decided to substitute the Cointreau with Kahlua.  I then built the drink over ice by pouring the Bailey's first, then the Grand Marnier, and the Kahlua last.

The drink curdled.  Badly.  The taste was fine, but the texture was disgusting!  Ultimately, the drink was undrinkable and I gave it to my sink.  Sad.

Desiring to get the nasty feeling out of my mouth I made another, this time using the IBA ingredients.  I built the drink in the order the ingredients had been listed: Cointreau, Bailey's, Grand Marnier.  Actually, I got that wrong... I put the Grand Marnier in first.  I'm not sure it matters, though.  Perhaps what matters is that the Bailey's was second, between the two liqueurs, and/or I wasn't using Kahlua.  The cocktail turned out much, much better.  No curdling.

Below is the official IBA recipe:

ORGASM (old fashioned glass )
3.0 cl Cointreau
3.0 cl Bailey's Irish Cream
2.0 cl Grand Marnier
Build all ingredients over ice in a old fashioned glass or shot glass. Garnish with cherry.
