The third degree of Freemasonry and the rigorous procedures to advance to that level. The term may have been coined by nineteenth century New York City Police detective Thomas F. Byrnes, perhaps as a pun on his name, as in third degree burns. The Knights of Columbus have a third degree ceremony which is required to advance to that level, seen as rigorous.
The bugle developed from early musical or communication instruments made of animal horns, with the word bugle itself coming from buculus, Latin for bullock (castrated bull).
The bugs mostly feed on the blood of humans, but they have been known to drink the blood of other animals, such as bats, guinea pigs, chicken, cats, dogs, certain birds and rodents. They can survive as much as a year without food, though spending such a long time without feeding is not typical.
