And you're sure you mean vomit?

Today, in class I asked "what does disappear mean?" The following conversation ensued.

Me: What does "disappear" mean?
Student: Vomit
Me: Vomit?
Student: Yes, vomit
Me: Wait, Vomit??
Student: Yeah, Vomit!!
Me: Vomit as in "bleghhhhhh?"
Student: No wait, ummm VANISH!

I was very amused. It was quite cute. Everyone laughed, luckily including her.
