Nasal mucus and emesis
What kind of question is this? Does this person really have nothing else to ask other than whether we say booger or barf? It’s actually a very good question and one that I’m qualified to answer. Yes, we say booger and barf all the time. It doesn’t matter how old we are, we’ll call mucus boogers and vomit barf.
There are plenty of synonyms for barf, like throw-up, chunks, last night’s dinner, etc. As for boogers, mucus just doesn’t have the same ring to it. If you know any other synonyms, please let me know. I’m always looking for new words to add to my vocabulary.
