If you're ever on the way back from Hawaii and happen to run into friends of yours that are in-costume Star Wars enthusiasts, it'd be wise not to use the native "Aloha" greeting.

You're looking for "Akbar."

"Akhbar" means "has more experience"

So what I was saying is "Allah has more experience"?

I guess it's not against the law to scream that.

Just don't shout at all, unless you need help.

Also, don't greet your friend Jack.

or any other Arabic words for that matter:

Some context:

https://www.theguardian.com/world/2016/dec/21/adam-saleh-del...

"A YouTube star known for filming elaborate hoaxes was escorted off a Delta flight on Wednesday morning after he claimed that other passengers complained when they heard him speaking in Arabic.

Adam Saleh, a 23-year-old YouTube star from New York, posted multiple videos to Twitter and Periscope on Tuesday, showing himself being escorted from a plane by Delta flight attendants.

Saleh said in the videos that after passengers heard him speaking Arabic, they “felt uncomfortable” and called flight attendants. However, while it is clear that he was removed from the flight at London’s Heathrow airport, the circumstances leading up to the video – retweeted more than 644,000 times – are not known and cannot be verified.

Saleh has created videos in the past that involved staged scenes on airplanes and with actors playing authority figures."
