Dipper rolls his eyes and looks back up at her. "Yes. Terrified. How would I recover from such a blow." The fact is, he knows plenty of girls who could beat him up, and also at least one gender-nonspecific individual who would have a decent shot, though Dipper maintains he could take Chara. He doesn't want to fight win or lose, but it's easier to be sarcastic than actually respond to her taunts. Dipper has in the past worried about not being masculine enough, but he's come a long way since then. The fact is, he doesn't want to fight right now. Anyone of any gender. He just wants to sit and feel miserable.
