A deathclaw is an enemy found and fought in the "Fallout" series by Bethesda. Deathclaws have a somewhat dinosaur-like apearance with a raptor like body, razor sharp teeth, horns, and trademark claws on each hand. They are incredibly fast, have incredibly high health and are known for forcing a player to waste a copious amount of ammunition for little reward other than experience. Any true Fallout player has had at least 3 nightmares involving deathclaws, bad condition power armor and nothing but a ten millimeter pistol.
1. A person who participate in extreme sports. For example, David Goggins once ran for 48 hours straight.
2. A person who applies the mentality of extreme sports into everyday life in order to appreciated the aesthetic values of life. For example, Byron's aesthete. Another example would be the half-fictional half-autobiographic character in Soren Kierkegaard's Diary Of A Seducer. Yet another example can be found in the works of Marquis de Sade.
John is such a badass deathlete - he crammed for 4 classes in the exam week and slept 10 hours in 10 days.
