Call a dwarf a slur, he’ll laugh and say “good one!”

Call an elf a slur and he’ll hold a grudge for 150 years

(Disclaimer: don’t call anyone slurs)

Call an elf a slur and he’ll hold a grudge for 150 years.

Call a dwarf a slur and he’ll write it down in the Book of Grudges and he and his kin will hold it against you and yours until the grudge is settled.
