Frigg was the goddess of marriage and justice. In Norse Mythology she was foremost among the goddesses and the wife of Odin (or
Wodin). Thor was either her brother or
stepson. Wednesday is named after Wodin, Thursday after Thor and Friday after Frigg.
The word
frigg has nothing to do with wanking or fucking and is not a substitute for these pleasures of the flesh. Like many four letter words it would have passed down into modern usage from the
Saxons/Vikings, and in sophisticated Norman England would have been considered as base and vulgar, a word used only by peasants.
Example:
Frigg had twelve handmaidens each with specialist powers. One of these for instance was Eir who was the god’s healer and it doesn’t take much imagination to visualise a
hoary Viking banging his thumb while mending his shield and screaming out. “Oh Frigg, it hurt.” Thus hoping she would send Eir to ease his throbbing digit. Hence the modern expression, “Oh
frigg it” when something goes wrong.
Similarly the same hoary Viking, when confronted with an enormous catastrophe like his
longboat capsizing in the middle of the North Sea full of pillaged gold would have cried out, “Oh Frigg where are you. Have you deserted us? Well you can go and rot in
Valhella” Obviously this is the root of the modern expression, “ Friggin Hell”, for something unbelievably surprising.
