chumming
When a fat nasty person eats food and gets shit all over their face, but they don't notice it and they just keep eating their food while you can't help but stare and vomit.
While Rachel was eating her sub a little mayonnaise dribbled down her face, but she didn't notice. Sean could only sit and stare in disgust and complete nausea as she kept chumming on her sub.
