I would probably scream and be all "Ew ew ew ew EW!!! get it off!!! ahhhh!!!! get it off me right now!!!" Then stay completely still and have my फ्रेंड्स like freakout with me bc i know they would :P In the end I would probably change into any clothes nearby as fast as possible!
i would freak out yelling "EW THATS SO GROSS!!!!! GET IT OFF ME!!!! GET IT OFF ME!!!!!!!!!! KYAAAAAAAA!!!!!!!!!!" then i would runt to the bathroom and take like,20 showers and baths the अगला day, i would kick the person that threw up on me on the face ninja style
Hmmm...my initial reaction would be disgust because, well, someone just got sick all over you. But then I'd put that aside, escort them somewhere else until they were finished, help them clean up, and then clean myself.
I've had it done to me. My brother couldn't handle the ride at the circus and I tasted his Burger King...I just kept my mouth shut so it would stop going in and then went to puke in the bathroom. Don't think I'll ever forget that one.
