A fight, where you use bottles instead of pillows to knock down your opponent. Normally happening in a bar or pub. Usually there will be only one winner, the last person standing in the room. There are rumours that it is an old lithuanina tradition, sometimes still executed in the lithuanian countryside.
"Hey, what happend to your face?" "I was in a Lithuanian Pillow Fight last night."
"Watch your mouth or we will soon have Lithuanian Pillow Fight in here!"
