She traded down. We get it, Taco Bell

So let's analyze this one to find what Taco Bell really thinks of it's demographic, shall we?

Cute girlfriend is out for a walk with her man-child new boyfriend, who is clearly a lot more into eating crap with both hands than being with her or taking care of himself.  They bump into her ex, who is a non-Taco Bell-eating, healthy fitness-oriented guy who, from his reaction to seeing a former girlfriend, has moved on and hasn't given her a second thought.

At this point, I assume that Ex Girlfriend wants very badly to show well to Ex Boyfriend, but since New Boyfriend is already Not Tall, Not Athletic and eating Taco Bell with both hands, the odds are pretty heavily stacked against her.  Still, if New Boyfriend can just manage to be coherent and sociable for a few seconds, this might not turn out too badly.

Instead, New Boyfriend inexplicably believes that Ex Boyfriend wants some kind of physical contact with him, and he's got his hands full of carbs and grease, so he gives him a chest bump.  This comes off as unbelievably stupid and embaressing to everyone involved, and has probably ended his relationship with New Girlfriend, though that's going to have to take place off screen, because Ex Girlfriend still needs to make the best of the situation until Ex Boyfriend is gone.

Ex Girlfriend links her arm with Soon to Be Latest Ex Boyfriend and rather defensively moves on- as I implied, she can't break up with this clueless slob on the spot, otherwise hunky Ex Boyfriend jogs away the victor of the moment.  She must pretend that they are still a couple for at least a few more seconds, or until Ex Boyfriend is out of earshot.

But please, tell me that inside of three minutes this girl- who can clearly do much better- has dumped her latest mistake's sorry ass right there in the park.  Please tell me she isn't this desperate for a guy to hook arms with just in case she runs into Jogger Ex.  Please tell me she isn't THAT sad.
