Never show your teeth if you smile at a gnoll - this is intepreted as a threat (ie saying I will eat you) and will result in attack
If a Gnolll chews a peice of meat, spits it out and then offers it to you - this is a sign of great affection (female gnolls chew the meat of their young). If you refuse the Gnoll will be offended and attack!
Gnolls eat their dead (and anything else dead or even half dead for that matter)
Rotten food is a delicacy (Yummy! look at the maggots in this beef Mavis - delicious!")

Gnolls have much in common with hyenas, which are by nature sscavengers. I found the above customs on another thread they make a certain sense. So gnolls in the last lands are scavengers and act like it, eating pretty much any type of meat that is not actually poisonous, the stinkier and "riper" the better. Gnolls in Shosnar who have obtained some wealth and social status may follow the Thosian customs for the burial of the dead, but those of the lower castes cannibalize their dead and simply bury the bones in urns. Gnolls are naturally greedy and only share food with those they are very close to, which they may pre-chew to soften before sharing.
