Fart, rip, flatulence. Derived from the verb пердеть (to fart), which shares Proto-Indo-European roots with words like fart. Heavily vulgar, informal, and used both literally and figuratively to describe nonsense, bad music, or boring talk.
Почему пердеж то жутко воняет, то совершенно нейтрален? Как добиться постоянства?
Why do some farts stink horribly while others are completely neutral? How do you achieve consistency?
