Slang term in the UK, Australia and some other Commonwealth countries. Very, very common. Is NOT the alternative to "fucking" because it is more in the range of offense to "damn".
Used before a word to make it more angry, appealing, exaggerative, etc.
Archaic swearword originating in England, originating from the even more archaic phrase 'By God's blood', but nobody really knows that or cares. DOESN'T mean 'fucking' you screwheads.. We use that word too!
Why the hell is this 'example too short?' I swear, if this one doesn't work, I am going to track down those urbandictionary guys and use their spines as glockenspiels
