Instead of taking
stuff away from a grave (grave robbing) you are adding to the grave site.
Usually taking the form of revenge; by having lunch sat on their grave, tossing all the empty
beer cans, wrappers, and crumbs over it. Then lighting up a few smokes flicking the ash about and grinding the
butt into the headstone.
To finish you can then urinate and/or take a dump on the grave, using the flowers or cards to wipe with.
Steve 'Hey
dude do you feel
bad you will never get your
revenge on Mike for bullying you?'.
John 'Naw I spent my lunch grave slobbing his plot , so it's all good now'.
