Louiseaj08, can you explain a bit more about where you found this? You are quite sure that it isn't a trip, so you must have some idea of what it might well be.
You will notice that I have changed the title to comply with rule 4 "Put the word or phrase in the title when asking a question (Avoid "translation please", "how do I say this?", "does this word exist?", "I'm new" and similar expressions)."
