Honestly you should just learn to blurt out really humiliating stuff in ways that will sabotage you. Sure you might be scared at first but eventually you’ll just be saying it to every random hot girl you see.
You could say something like “wouldn’t it be humiliating if you made me pay for your shoes and you stomped on my balls with them?”
You’d get bonus points for offering to pay AND you’d get a hot girls spit in your face LOL
And because I’m such a good friend I’m gonna suggest that we just practice here at my place.
Oh no… Oh no are you actually jizzing right now? LOL!
