Severe fear of throwing up or being near vomit. Most people with emetophobia can’t stand to be around other people who are feeling ill, for fear of them puking
Friend- "why do you dislike going to the school nurse?"

Caveat Emptor is latin for "let the buyer beware" and is the basic idea that a buyer should closely examine every item and purchase they make as if they are about to beripped off, making purchasing safer.
I gave my credit card number to some website to purchase something and the owner charged up my card. Well, as they say; Caveat Emptor.
