If you die in a battlefield (or possibly anywhere in PvP), your buff timers get altered. The Meatlump Kiss buff seems to be bugged and have a timer of over 90,000 hours after you clone in a BF.
Just happened to me, the buff does indeed stick in your stats. Not sure if it's repeatable, give it a try!
NOTE: This lasts through logging out! I went offline for a few hours, came back and still over 90,000 hours on the +100 luck buff. Best to stay away from the public or to be a spy, as this buff is blatantly a bug!
