Hi Nadia As Zargham points out there is the noun 'hangover' in English BUT I don't think this is what the person means in this context, especially as in the sentence you have given 'hang over with' is being used as a verb. Where does this sentence come from? I think it might be somebody confusing some common phrasal verbs. They are as follows: hang around with/ hang out with - to be with another person or group for a period of time sleepover/stay over - stay a night at someone else's house They seem to be trying to say they are going to spend some time, perhaps a night, with someone else, but they're not really using the correct phrasal verb Note: the phrasal verb 'hang over' (not 'hang over with) does exist but has a completely different meaning which doesn't make sense in this context

It's hangover. And here your answer. http://www.merriam-webster.com/dictionary/hangover
