Do you consider looking up a word cheating?

If you have no idea what a word means do you look it up? Curious to know if that is that considered cheating by the community. I like to play an honest game, but if I genuinely don't know what a word means, I will look it up. Friends say I am cheating, but it doesnt necessarily give me an answer to the connection. Example on today's puzzle is Tchotchke. What's the concensus here?
