Irish name derived from the "Salmon of Knowledge" an old Celtic mythological story. King Fin turns into a Salmon to escape his enemies amd eats the hazelnuts that drop from the tree of Knowledge into the river. By eating them he has ultimate Knowledge. Eventually he gets caught and cooked the cook (Fin again in a new life) burns his thumb on the cooked fish and sucks it. He then knows everything.
As above example - no more to say

Irish name derived from the "the jiblet" an old Celtic mythological story. King Fin turns into a jiblet and goes on to wreck everyones head. His enemies are many because most people are shit sick of him. He is an incredible jew who loves to spend very little. People have decided he must die on many occasions but eventually came to the knowlegde that everyone needs someone to hate. Quote" haterz be hatin' yo!" Fintans were more likely to be part of the hitler youth and grow up to the S.S. In modern times a fintan is likely to have no "nads" a tiny weiner and watch a rake of porn.
