Alpha Phi Omega: National Co-ed service fraternity. Largest largest collegiate fraternity in the US. Founded on the 3 cardinal principals of Leadership, Friendship, and Service. Unlike many other fraternities, APO's primary focus is to provide volunteer service within four areas: service to the community, service to the campus, service to the fraternity, and service to the nation as participating citizens.

Bengali word for sister. Except you don't use it unless you love your sister too much. Just like Jaime Lannister loves his sister Cersei Lannister in Game of Thrones. You could use this in a sentence like "Thanks apo apnio" which conveys the utmost form of gratitude towards the apo you are addressing.
Girl: Wow! You make killer memes!
Boy: Thanks apo apnio.
Girl: Don't come near me or my city ever again.
Boy: Thanks apo apnio.
Girl: Don't come near me or my city ever again.
