(verb)- To Jump Out Loud
to be so impressed by a person's knowledge of Hungarian that you literally jump out of your seat.
So there I was, minding my own business, when my bffl came on Facebook. I thought I would converse with her using basic Hungarian phrases, but her brother actually knows some complex Hungarian. He was like 'Értem' and I was all like 'JOL!' and I hit my head on a low-hanging beam.
