FARM
“farm”
How to make it
Draw the thumb of an open '5' hand across your chin from one side to the other.
Where the sign comes from
UnknownNo reliable source. We'd rather say so than invent one.

No sources — which is the point of the “unknown” tier. If you know of a documented account, the historical databases are where to check it.
The sign, taken apart
