Shirt a girl wears that belong to her boyfriend and therefore most likely 10x larger than her body size. May also stink with sweat or possess an overpowering smell of cologne depending on her boyfriend's hygiene.
"나은 had been wearing that boyfriend shirt everywhere for 3 months now... to the bus, her workplace, and even to the mall. She should probably wash it already."
