Properly, it is a French Canadian side dish often served as a complete meal (which along with Export A "green death" cigarettes explains why Quebec leads the nation in heart disease) consisting of french fries mixed with cheese curds which are then melted by pouring on gravy. The term is now often applied to any combination of fries, cheese, and gravy.
Now here is a little tidbit of California law (only because it was the first US state google showed me):
1563. (a) This article shall not be interpreted to require tender
or payment of more than one witness fee and one mileage fee or other
charge, to a witness or witness' business, unless there is an
agreement to the contrary between the witness and the requesting
party.
(b) All reasonable costs incurred in a civil proceeding by any
witness which is not a party with respect to the production of all or
any part of business records the production of which is requested
pursuant to a subpoena duces tecum may be charged against the party
serving the subpoena duces tecum.
(1) "Reasonable cost," as used in this section, shall include, but
not be limited to, the following specific costs: ten cents ($0.10)
per page for standard reproduction of documents of a size 8 1/2 by 14
inches or less; twenty cents ($0.20) per page for copying of
documents from microfilm; actual costs for the reproduction of
oversize documents or the reproduction of documents requiring special
processing which are made in response to a subpoena; reasonable
clerical costs incurred in locating and making the records available
to be billed at the maximum rate of twenty-four dollars ($24) per
hour per person, computed on the basis of six dollars ($6) per
quarter hour or fraction thereof; actual postage charges; and the
actual cost, if any, charged to the witness by a third person for the
retrieval and return of records held offsite by that third person.
(2) The requesting party, or the requesting party's deposition
officer, shall not be required to pay those costs or any estimate
thereof prior to the time the records are available for delivery
pursuant to the subpoena, but the witness may demand payment of costs
pursuant to this section simultaneous with actual delivery of the
subpoenaed records, and until payment is made, is under no obligation
to deliver the records.
So if you are really afraid all your posts may be subpoenaed, post often, especially to long threads like those in ICR. Firstly it will be of help to others, and secondly I am sure the entire thread should be printed for context. This will lead to an enormous legal bill sorting through everything, and help support SI as well as I am sure that $24 per hour while the printer is running and 20 cents per page will result in some surplus that can go towards site maintenance. Only a fool would subpoena records from DS or Meta.
