Meaning approximatly "fear(s) nothing", the word first came into use as a name for a class of large (sail) ships, dominant during the early 20:th century. The word has often appeared (occationally with slight difference in spelling, e.g. Dreadnaught).

Examples of modernised usage include (different, fictional) classes of ships, especially spacecraft within various sci-fi franchises, Spacemarine Dreadnoughts from GW:s Warhammer 40K franchise (sarcophagus-like warmachines which hold the remains of fallen, near-incapacitated heroes of the Imperium) and a guitar body. The word also commonly appears as a synonym for just about anything "big" or, in some cases, strong, impressive of awe-inspiring.

An amazing male, whom is very sweet, kind, and loveable. Your best friend, and mentor... That guy you just want to hug and hug and hug forever...

That loves you fully, but let would let you go out with his best friend, because he's just that kind of guy... Even though you eventually end up being with him.
