Just like Cha-ha. A word that means, Im really laughing but totally not. It can be used as a cover up word. If you didnt mean to say whatever just came out of your mouth, you can cover it up with an ar gar. Also, you can use ar gar as a surfer laugh. Just like cha ha. Like..cha ha that was great. Surfs up, ar gar.
Ar gar. I'm such a retard.
Ar gar. That was like, sooo funny.
Ar gar. (I didnt really mean to say that but it came out anyway so I'll cover it up with Ar gar)

This guy was looking at me at the pub all night and I thought he looked like an ars, but when he came and talked to me he totally redeemed himself as an ars poetic!
