Acronym - Friendly Local Game Store/Shop. Usually seen on message boards and mailing lists.
I picked up the latest ish of Dork Tower at my FLGS.
Fun Loving Geeks - the name given to generally intelligent and fun un-stereotyped friends who go on big group outings such as:
Harry Potter back-row takeover,
Drayton Manor in the rain,
Twister down Riv,
FLG Burning of the Books,
Random house parties.
Word is spread mainly by e-mail and outings are organised amazingly by a small person with a hat named Desmond.
The name originates from the band 'Fun Lovin' Criminals', no-one's quite sure why.
"Party round mine next week!"
"Inviting the FLGs?"
