I love a pseudo ASCII strategy game Dwarf Fortress and generally sympathize dwarves.
These icons can be used for an ability, spell or a very angry dwarf.
I use it for a "Tantrum" ability which should turn you within 5 sec against the closest creature (friend or foe) if someone of your comrades dies (you gain buffed hp and damage); although it's not scripted yet... But the icon is here!
Enjoy the bloody rage.
