*SPOILER* Apparently Chad was so nervous for the 日期 that he drank water continuously during the date. So when Chad was like: "Sonny, can I ask 你 something?", Sonny went very "hot" and did one of those "popular girl" hair flips while going "Yes, Chad?", startling him, and he starts puking on Sonny..... Watch the part 2 in the vids.
Obviously because its there first 日期 they are both really nervous, so they keep on talking to their selfs and Chad can't stop drinking water and he says to himself "Tell her that she makes 你 nervous, she'll understand." so he says to Sonny, "Sonny, I need to tell 你 something," Which Sonny 回复 with (in a 'hot' way) "Yes, Chad?". Chad becomes even 更多 nervous and vomits on Sonny, Chad quickly leaves because of what had just happened, Sonny says to herself "Oh my gosh, I can't believe he just did that! Why am I saying this to myself!" Then she shouts out "Oh my gosh, I can't believe 你 just did that!"
