An abbreviation of the name
Oskar. Someone very feminine who enjoys the company of men over women. You can differentiate an Osku from a crowd by his face mask which
holsters a ":3" face. If this doesn't work you can yell out "Who wants to
play Rainbow Six Siege?", since femboys love the game.
Person 1: Hey, are you an Osku?
Osku:
How could you tell, daddy?
UwU You want
a piece of me? :3
