Okay then, in that case the commenter should tell his date that he has bubble guts and needs to go home early but that he had fun and would like to go out again next week or sometime.

The point is that trying to play it off and ending up seeming to shut down suddenly and then suffer through for a bit before inexplicably leaving early is way worse than simply being honest even if it might sound disgusting.

If she's grossed out by farts or doesn't want to date you again because something you ate gave you diarrhea, then she's not marriage material. How do you expect that to go when you're living together for the rest of your lives?
