The name "Rambo" is from an unknown origin so far. It can be dated back to the 17th century Swedish immigrant Peter Gunnarsson Rambo.
"Rambo" is also the name of an old farm in Vestfold county, Norway ("Rambøe" 1664, "Ramboe" 1723) - and about 65 people in Norway have Rambo as a family name. The Norse form of the name might have been *Hrafnabú. The first element is then the genitive pluralis of hrafn m 'raven', and the last element is bú n 'farm'. The name was brought to the US by Norwegian settlers.
- (figuratively) One who is reckless, disregards orders, uses violence to solve all problems, and bravely charges headlong into the teeth of the enemy.
