I just quote: "A cultural bump is an occurrence when an individual finds himself or herself in a situation (that is) different, strange, or uncomfortable when interacting with persons of a different culture. This phenomenon results from a difference in the way people from one culture behave from people in another culture"
Cross-cultural communication is probably the communication relating to two or more cultures. OR maybe any type of communication (for example commercial) in which many cultures are involved!! This one needs to be confirmed!
