A person who
everyone wants to
have sex with, and most likely will.
Mosienko can usually be summed up in
one word: sex.
However, Mosienkos are also known for being sexilicious and in popular demand, this usually leads to wild, drunken licentious festivity and revelry. In other words: sex orgies.

Guy: "
Holy FUCK, that WAS a great Mosienko."
