Nah cause you don't have the power to force her to date you as an alternative to drinking the pesticide, so it wouldn't work.
Try kidnapping her, typing her up and dangling your peepee over her, along with a bottle of pesticide ready to be opened over her mouth, then see what she chooses. Then you would find out that it's actually a figure of speech and you're kind of retarded for wondering if she would actually choose death over dating an incel just because she said that.
