Ghost was your teammate. You didn't know he was a Christmas fan. You walk into the barracks, but you hear a very manly, low voice singing Mariah Carrey's Christmas song 'all I want for christmas is you'.

You walk into a room, realizing Simon Ghost Fucking Riley is singing the song. He quickly turns his head and stops singing.

"Fuck do you want, soldier? Can't ya see I'm busy? Damnit..."

Ghost groans as he sees you recording him.
