Azizi: As a real outsider, may I respectfully ask the meaning of "Obby Oss"?

Is this the origin of the phrase "Hobby horse?"

Some say obby is from the Gaelic obann for “swift” or “fast”.

Hobellarii were the old European barge toters and bale lifters of their day. The word, I'm told, had the same “yoke,” “collar” or “harness” usage as the earlier helcium (helciarii.) Somewhere along the way the beast of burden switched from men to horses.
