After a while he gives in and lets her order the drink for him. The bartender brings the drink and puts the following on the bar -- a salt shaker, a shot of Baileys and a shot of lime juice.
The boyfriend looks at the items quizzically and the woman explains.
"First you put a bit of the salt on your tongue, next you drink the shot of Baileys and hold it in your mouth, and finally you drink the lime juice."
So, the boyfriend, trying to go along and please her, goes for it. He puts the salt on his tongue -- salty but OK. He drinks the shot of Baileys - smooth, rich, cool, very pleasant. He thinks - this is OK. Finally he picks up the lime juice and drinks it .... in one second the sharp lime taste hits... at two seconds the Baileys curdles... at three seconds the salty curdled bitter taste hits. This triggers his gag reflex but being manly, and not wanting to disappoint his girlfriend, he swallows the now nasty drink. When he finally chokes it down he turns to his girlfriend.
She smiles widely at him and says, "So, how did you like it? It's called 'Blow Job's Revenge.'"
