The well known rule that fat people may make
fat jokes or comments at other fat people without offending them.
It is not
required to say "
Universal Fat Guy Rule" after a big guy makes a comment to another, nor is it to just say "UFGR".
Skinny Guy: Nice moobs, Joe!
Joe (Who's a hefty fellow) : *punch
to the face*
Harold (Also a big guy): Nice moobs, Joe!
Joe: *starts to look offended, but remembers the
Universal Fat Guy Rule* "Thanks!"
