B-29 

Unlike most retarded things in the Urban Dictionary, this word is legit, actually it’s just a plane. The Boeing B-29 Superfortress is a 1944 bomber and was the the most advanced allied bomber of World War II. It is most famous for dropping the two atomic bombs over Hiroshima and Nagasaki, Japan. It was the first plane to be able to escort and drop an atomic bomb. P.S. It is a common misconception that the B-29 “Enola Gay” dropped both of the atomic bombs when actually the “Enola Gay” only bombed Hiroshima while another B-29 codenamed “Bockscar” dropped the atomic bomb on Nagasaki.

Boeing built the B-29.

A poop splash so big it gets onto and dirties the toilet seat.

Ugh, someone pulled a B-29 in the restroom and I had to to hover to do my business.
