look up any word, like bukkake:
 
1.
Boeing six engine jet bomber which entered service in 1951 and lasted until 1966. It was the backbone of SAC's(Strategic Air Command) deterrent force until the early sixties. It is also the direct ancestor of the B-52, KC-135, and the indirect ancestor of every modern jet transport except the Concord. One hell of an airplane. It was called the Stratojet.
The B-47 had only a three man crew.

mean guy: *roffles* I'd never tell someone like you.
